Replace the per-frame uniform list with stable, name-cached handles that retain their values across shader recompilation. Track dirty uniforms so only changed values are uploaded, reducing redundant GL calls and buffer management. Add a reusable effect-pass pipeline with per-pass shaders, samplers, formats, resolutions, and intermediate render targets. This makes external effects easier to integrate and supports arbitrary multipass chains. Migrate the desktop, cursor, damage, 24-bit, downscale, CAS, and FSR rendering paths to the new APIs. Also ensure framebuffer objects are released correctly.
