-[![Build status](https://ci.appveyor.com/api/projects/status/0kf0ct9831i5l6sp/branch/master?svg=true)](https://ci.appveyor.com/project/elmindreda/glfw)
-[![Coverity Scan](https://scan.coverity.com/projects/4884/badge.svg)](https://scan.coverity.com/projects/glfw-glfw)
+This directory contains a modification of GLFW, whose official website and
+upstream repository are https://glfw.org and https://github.com/glfw/glfw,
+respectively.

-## Introduction
+In this modification, some static functions sharing the same name in different
+platforms have been renamed so all of GLFW's source files can be combined into
+one (as done by ``rglfw.c``). Also, the Null platform, which is not used by
+raylib, has been disabled. The renamed functions are:

-GLFW is an Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan
-application development.  It provides a simple, platform-independent API for
-creating windows, contexts and surfaces, reading input, handling events, etc.
-
-GLFW natively supports Windows, macOS and Linux and other Unix-like systems.  On
-Linux both X11 and Wayland are supported.
-
-GLFW is licensed under the [zlib/libpng
-license](https://www.glfw.org/license.html).
-
-You can [download](https://www.glfw.org/download.html) the latest stable release
-as source or Windows binaries, or fetch the `latest` branch from GitHub.  Each
-release starting with 3.0 also has a corresponding [annotated
-tag](https://github.com/glfw/glfw/releases) with source and binary archives.
-
-The [documentation](https://www.glfw.org/docs/latest/) is available online and is
-included in all source and binary archives.  See the [release
-notes](https://www.glfw.org/docs/latest/news.html) for new features, caveats and
-deprecations in the latest release.  For more details see the [version
-history](https://www.glfw.org/changelog.html).
-
-The `master` branch is the stable integration branch and _should_ always compile
-and run on all supported platforms, although details of newly added features may
-change until they have been included in a release.  New features and many bug
-fixes live in [other branches](https://github.com/glfw/glfw/branches/all) until
-they are stable enough to merge.
-
-If you are new to GLFW, you may find the
-[tutorial](https://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful.  If
-you have used GLFW 2 in the past, there is a [transition
-guide](https://www.glfw.org/docs/latest/moving.html) for moving to the GLFW
-3 API.
-
-GLFW exists because of the contributions of [many people](CONTRIBUTORS.md)
-around the world, whether by reporting bugs, providing community support, adding
-features, reviewing or testing code, debugging, proofreading docs, suggesting
-features or fixing bugs.
-
-
-## Compiling GLFW
-
-GLFW itself requires only the headers and libraries for your OS and window
-system.  It does not need the headers for any context creation API (WGL, GLX,
-EGL, NSGL, OSMesa) or rendering API (OpenGL, OpenGL ES, Vulkan) to enable
-support for them.
-
-GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and
-MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC
-and Clang.  It will likely compile in other environments as well, but this is
-not regularly tested.
-
-There are [pre-compiled Windows binaries](https://www.glfw.org/download.html)
-available for all supported compilers.
-
-See the [compilation guide](https://www.glfw.org/docs/latest/compile.html) for
-more information about how to compile GLFW yourself.
-
-
-## Using GLFW
-
-See the [documentation](https://www.glfw.org/docs/latest/) for tutorials, guides
-and the API reference.
-
-
-## Contributing to GLFW
-
-See the [contribution
-guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for
-more information.
-
-
-## System requirements
-
-GLFW supports Windows XP and later and macOS 10.8 and later.  Linux and other
-Unix-like systems running the X Window System are supported even without
-a desktop environment or modern extensions, although some features require
-a running window or clipboard manager.  The OSMesa backend requires Mesa 6.3.
-
-See the [compatibility guide](https://www.glfw.org/docs/latest/compat.html)
-in the documentation for more information.
-
-
-## Dependencies
-
-GLFW itself needs only CMake 3.1 or later and the headers and libraries for your
-OS and window system.
-
-The examples and test programs depend on a number of tiny libraries.  These are
-located in the `deps/` directory.
-
- - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples
-   with command-line options
- - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded
-   examples
- - [glad2](https://github.com/Dav1dde/glad) for loading OpenGL and Vulkan
-   functions
- - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in
-   examples
- - [Nuklear](https://github.com/Immediate-Mode-UI/Nuklear) for test and example UI
- - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk
-
-The documentation is generated with [Doxygen](https://doxygen.org/) if CMake can
-find that tool.
-
-
-## Reporting bugs
-
-Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues).

+    This protocol allows a compositor to suggest for surfaces to render at
+    fractional scales.
+
+    A client can submit scaled content by utilizing wp_viewport. This is done by
+    creating a wp_viewport object for the surface and setting the destination
+    rectangle to the surface size before the scale factor is applied.
+
+    The buffer size is calculated by multiplying the surface size by the
+    intended scale.
+
+    The wl_surface buffer scale should remain set to 1.
+
+    If a surface has a surface-local size of 100 px by 50 px and wishes to
+    submit buffers with a scale of 1.5, then a buffer of 150px by 75 px should
+    be used and the wp_viewport destination rectangle should be 100 px by 50 px.
+
+    For toplevel surfaces, the size is rounded halfway away from zero. The
+    rounding algorithm for subsurface position and size is not defined.

+  <description summary="protocol for constraining pointer motions">
+    This protocol specifies a set of interfaces used for adding constraints to
+    the motion of a pointer. Possible constraints include confining pointer
+    motions to a given region, or locking it to its current position.
+
+    In order to constrain the pointer, a client must first bind the global
+    interface "wp_pointer_constraints" which, if a compositor supports pointer
+    constraints, is exposed by the registry. Using the bound global object, the
+    client uses the request that corresponds to the type of constraint it wants
+    to make. See wp_pointer_constraints for more details.

+	sends a locked event.
+

+	lock that will never activate.
+
+	There may not be another pointer constraint of any kind requested or

+

+
+	The request creates a new object wp_locked_pointer which is used to

+  <description summary="protocol for relative pointer motion events">
+    This protocol specifies a set of interfaces used for making clients able to
+    receive relative pointer events not obstructed by barriers (such as the
+    monitor edge or other pointer barriers).
+
+    To start receiving relative pointer events, a client must first bind the
+    global interface "wp_relative_pointer_manager" which, if a compositor
+    supports relative pointer motion events, is exposed by the registry. After
+    having created the relative pointer manager proxy object, the client uses
+    it to create the actual relative pointer object using the
+    "get_relative_pointer" request given a wl_pointer. The relative pointer
+    motion events will then, when applicable, be transmitted via the proxy of
+    the newly created relative pointer object. See the documentation of the
+    relative pointer interface for more details.
+
+    Warning! The protocol described in this file is experimental and backward
+    incompatible changes may be made. Backward compatible changes may be added
+    together with the corresponding interface version bump. Backward
+    incompatible changes are done by bumping the version number in the protocol
+    and interface names and resetting the interface version. Once the protocol
+    is to be declared stable, the 'z' prefix and the version number in the
+    protocol and interface names are removed and the interface version number is
+    reset.

+    <description summary="crop and scale interface to a wl_surface">
+      An additional interface to a wl_surface object, which allows the
+      client to specify the cropping and scaling of the surface
+      contents.
+
+      This interface works with two concepts: the source rectangle (src_x,
+      src_y, src_width, src_height), and the destination size (dst_width,
+      dst_height). The contents of the source rectangle are scaled to the
+      destination size, and content outside the source rectangle is ignored.
+      This state is double-buffered, and is applied on the next
+      wl_surface.commit.
+
+      The two parts of crop and scale state are independent: the source
+      rectangle, and the destination size. Initially both are unset, that
+      is, no scaling is applied. The whole of the current wl_buffer is
+      used as the source, and the surface size is as defined in
+      wl_surface.attach.
+
+      If the destination size is set, it causes the surface size to become
+      dst_width, dst_height. The source (rectangle) is scaled to exactly
+      this size. This overrides whatever the attached wl_buffer size is,
+      unless the wl_buffer is NULL. If the wl_buffer is NULL, the surface
+      has no content and therefore no size. Otherwise, the size is always
+      at least 1x1 in surface local coordinates.
+
+      If the source rectangle is set, it defines what area of the wl_buffer is
+      taken as the source. If the source rectangle is set and the destination
+      size is not set, then src_width and src_height must be integers, and the
+      surface size becomes the source rectangle size. This results in cropping
+      without scaling. If src_width or src_height are not integers and
+      destination size is not set, the bad_size protocol error is raised when
+      the surface state is applied.
+
+      The coordinate transformations from buffer pixel coordinates up to
+      the surface-local coordinates happen in the following order:
+        1. buffer_transform (wl_surface.set_buffer_transform)
+        2. buffer_scale (wl_surface.set_buffer_scale)
+        3. crop and scale (wp_viewport.set*)
+      This means, that the source rectangle coordinates of crop and scale
+      are given in the coordinates after the buffer transform and scale,
+      i.e. in the coordinates that would be the surface-local coordinates
+      if the crop and scale was not applied.
+
+      If src_x or src_y are negative, the bad_value protocol error is raised.
+      Otherwise, if the source rectangle is partially or completely outside of
+      the non-NULL wl_buffer, then the out_of_buffer protocol error is raised
+      when the surface state is applied. A NULL wl_buffer does not raise the
+      out_of_buffer error.
+
+      If the wl_surface associated with the wp_viewport is destroyed,
+      all wp_viewport requests except 'destroy' raise the protocol error
+      no_surface.
+
+      If the wp_viewport object is destroyed, the crop and scale
+      state is removed from the wl_surface. The change will be applied
+      on the next wl_surface.commit.

+
+  <description summary="Protocol for requesting activation of surfaces">
+    The way for a client to pass focus to another toplevel is as follows.
+
+    The client that intends to activate another toplevel uses the
+    xdg_activation_v1.get_activation_token request to get an activation token.
+    This token is then forwarded to the client, which is supposed to activate
+    one of its surfaces, through a separate band of communication.
+
+    One established way of doing this is through the XDG_ACTIVATION_TOKEN
+    environment variable of a newly launched child process. The child process
+    should unset the environment variable again right after reading it out in
+    order to avoid propagating it to other child processes.
+
+    Another established way exists for Applications implementing the D-Bus
+    interface org.freedesktop.Application, which should get their token under
+    activation-token on their platform_data.
+
+    In general activation tokens may be transferred across clients through
+    means not described in this protocol.
+
+    The client to be activated will then pass the token
+    it received to the xdg_activation_v1.activate request. The compositor can
+    then use this token to decide how to react to the activation request.
+
+    The token the activating client gets may be ineffective either already at
+    the time it receives it, for example if it was not focused, for focus
+    stealing prevention. The activating client will have no way to discover
+    the validity of the token, and may still forward it to the to be activated
+    client.
+
+    The created activation token may optionally get information attached to it
+    that can be used by the compositor to identify the application that we
+    intend to activate. This can for example be used to display a visual hint
+    about what application is being started.
+
+    Warning! The protocol described in this file is currently in the testing
+    phase. Backward compatible changes may be added together with the
+    corresponding interface version bump. Backward incompatible changes can
+    only be done by creating a new major version of the extension.

+    <description summary="window decoration manager">
+      This interface allows a compositor to announce support for server-side
+      decorations.
+
+      A window decoration is a set of window controls as deemed appropriate by
+      the party managing them, such as user interface components used to move,
+      resize and change a window's state.
+
+      A client can use this protocol to request being decorated by a supporting
+      compositor.
+
+      If compositor and client do not negotiate the use of a server-side
+      decoration using this protocol, clients continue to self-decorate as they
+      see fit.
+
+      Warning! The protocol described in this file is experimental and
+      backward incompatible changes may be made. Backward compatible changes
+      may be added together with the corresponding interface version bump.
+      Backward incompatible changes are done by bumping the version number in
+      the protocol and interface names and resetting the interface version.
+      Once the protocol is to be declared stable, the 'z' prefix and the
+      version number in the protocol and interface names are removed and the
+      interface version number is reset.
