Quantum e70cfd84fb [client] egl: use eglSwapBuffersWithDamageKHR for cursor-only updates
Instead of damaging the entire surface when rendering a cursor move,
we can use the EGL_KHR_swap_buffers_with_damage extension to only
damage the part of the window covered by the cursor. This should
reduce the cursor movement latency on Wayland.
