ADDED: `rlUnloadShader()` to unload shaders (that function was missing and compute shaders leak memory)
RENAMED: `rlCompileShader()` to p `rlLoadShader()` to be consistent with `rlUnloadShader()`
RENAMED: `rlLoadShaderCode()` to `rlLoadShaderProgram()`, more descriptive of return
RENAMED: `rlLoadShaderProgram()` to `rlLoadShaderProgramEx()`
RENAMED: `rlLoadComputeShaderProgram()` to `rlLoadShaderProgramCompute()`
RENAMED: Some functions parameters for consistency

* added cel-shading and outline using inverted hull example

* new screenshot

* added glsl100+120 compat

* updated view

* unnecessary spacing

REVIEWED: Reorganized structures for a clearer distinction between "skeleton", "skin" and "skinning" data
ADDED: New structures: `ModelSkeleton`, `ModelAnimPose` (alias `Transform*`)
ADDED: Runtime data `currentPose` and `boneMatrices` to `Model` structure
ADDED: Support animation frames-blending, for timing control
ADDED: Support animations blending, between two animations
REVIEWED: All models animation loading functions
ADDED: `UpdateModelAnimationEx()` for two animations blending
REMOVED: `UpdateModelAnimationBones*()`, simplified API
REVIEWED: Shader attributes/uniforms names for animations, for consistency
REVIEWED: Multiple tweaks on animations loading for consistency between formats
ADDED: example: `models_animation_timing`
ADDED: example: `models_animation_blending`
REVIEWED: example: `models_animation_gpu_skinning`
REVIEWED: example: `models_animation_blend_custom`
REVIEWED: All animated models loading examples

- Demonstrates per-bone animation blending for smooth transitions
- Supports upper/lower body selective blending (walk + attack)
- Includes uniform blending mode for comparison
- Uses GPU skinning for performance
- Follows raylib example conventions
