Quantum	2dca056526	[client] egl: refactor damage mesh generation into desktop_rects ... This mesh will later be used to render only damaged portions of the desktop. We also moved the coordinate transformation for damage overlay into a matrix and computed by the shader.	2021-08-03 21:37:31 +10:00
Quantum	5d5e4ede1a	[client] egl: use new EGL damage count semantics ... After the damage queue PR, EGL damage count 0 means no change, and -1 means invalidate the entire window. However, several other places have different semantics, and we are not handling them correctly: 1. KVMFR uses 0 to signal invalidating the entire frame, so if we receive 0 rectangles in egl_on_frame, we should set damage count to -1. 2. The damage overlay treated 0 as full damage, which is now incorrect. This is fixed, and now it treats 0 as no update, and -1 as full damage.	2021-08-03 00:57:32 +10:00
