* 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
* [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
