* Fix DrawSphereWires (Less aggressively)
Summary:
- Eliminated some redundancies
- Fixed a bug(?) where the sphere would have 1 more "ring" (latitude division) than expected
- Fixed a bug where the top ring was double-covered
- Added comments denoting which code draws which lines
* DrawSphereWires + DrawSphereEx parity
Summary:
- Replaced DrawSphereWires algorithm with one based on the much faster algorithm from DrawSphereEx
- Fixed +1 ring quirk on DrawSphereEx to match the change made to DrawSphereWires
Have the model animation update functions check the current shader to see if they are going to do GPU skinning or not.
Lazy load the CPU animation buffers so they don't get allocated if the user is doing GPU skinning.
This change allows both GPU and CPU skinning in the same program.
* [rmodels] Fix glTF skinning when joints have non-joint parent nodes
Some glTF exporters (notably wow.export, but also various other DCC pipelines) place skin joints under intermediate non-joint transform nodes that carry part of the bind-pose offset. raylib's existing LoadBoneInfoGLTF and LoadModelAnimationsGLTF only inspected a joint's immediate parent and only sampled joint-local TRS, so any transform stored on an intermediate non-joint ancestor was silently dropped, producing exploded or stretched meshes at runtime.
Two surgical changes:
LoadBoneInfoGLTF: walk the parent chain past any non-joint ancestors when looking up parentIndex, instead of comparing only against node.parent. Joints whose direct parent is a non-joint were previously treated as skeleton roots.
LoadModelAnimationsGLTF: precompute a per-joint extOffset matrix that bakes in the static TRS contribution of any intermediate non-joint nodes between the joint and its nearest joint ancestor. Apply it to each frame's joint TRS before BuildPoseFromParentJoints so the per-frame world transforms match the bind-pose world transforms (LoadGLTF already used cgltf_node_transform_world for bindPose, so this aligns the two code paths).
The replaced root-only worldTransform adjustment is a strict subset of the new per-joint extOffset machinery, so it has been removed.
Spec-compliant files (the six skeletal-skinning .glb examples shipped with raylib) render bit-identically before and after; previously broken files (e.g. wow.export's babyoctopus.gltf) now match the reference rendering from f3d, the Khronos sample viewer, and three.js.
* Resolve review: NULL-check joint offset allocation, fail fast
[rmodels] Address review feedback on glTF joint offset handling
Resolve the open review points raised on PR #5876 for the per-joint
extOffset precompute in LoadModelAnimationsGLTF.
* NULL check: validate the extOffset RL_MALLOC result before use, which
was previously missing.
* Fail-fast handling: detect the allocation failure at its source and
abort animation loading (log a warning, free resources, return NULL)
instead of propagating a NULL pointer into the per-frame loop.
* Brace formatting: expand the collapsed one-line joint-match check
(if (...) { isJoint = true; break; }) into raylib's standard Allman
brace style.
* Readability: break the deeply nested MatrixMultiply(MatrixMultiply(...))
into named nodeScale/nodeRotation/nodeTranslation/nodeTransform locals,
mirroring the existing S/R/T composition later in the function.
* Spacing/line breaks: add blank lines within the precompute block to
match the surrounding code style.
Dropped the `11` relative to OpenGL 1.1 because latest `rlsw 1.5` also includes support for FBOs and could potentially implemented other higher level features in the feature, discerning from OpenGL 1.1 limitations
Redesigned to support disabling features on compilation with `-DSUPPORT_FEATURE=0`
REMOVED: `SUPPORT_DEFAULT_FONT`, always supported
REMOVED: `SUPPORT_IMAGE_MANIPULATION `, always supported
REMOVED: `SUPPORT_TEXT_MANIPULATION`, always supported
