Module gl_compositor 

OpenGL-style Compositor

Provides a GPU-accelerated compositing pipeline that manages surfaces, performs alpha-over blending, and renders to a back buffer. Uses the texture atlas for efficient surface packing and supports multiple blend modes with integer-only arithmetic.

All blending uses integer math: result = (src * alpha + dst * (255 - alpha)) / 255.
