- Create proper sprite shader (vs_sprite.sc, fs_sprite.sc) with GPU instancing - SpriteInstance struct now 80 bytes (5 x vec4) for GPU layout compatibility - Add BufferDesc::Layout enum (Raw, PosColor, InstanceData) for proper vertex layouts - BgfxDevice creates correct VertexLayout based on buffer type - SpritePass uses PosColor layout for quad vertices (Position + Color0) - Instance buffer uses 5 x vec4 layout (TexCoord7-3) for i_data0-4 - Add texture support with v_texcoord0 interpolation from instance UVs - Create default white 1x1 texture fallback - Compile shaders for SPIRV (Vulkan), GLSL (OpenGL), and Metal Visual test confirms sprites render correctly at ~545 FPS. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
