tdf#96385 - opengl: dynamically adjust priority of swap buffers.
Initially we start with a very low priority, so that the lame
bits of code that do eg. focus, and cursor rendering before the
document is visible do not cause a swap, flash. Then after we've
processed a REPAINT priority idle (hopefully our first paint) we
adjust the swap priority to highest.
Essentially a fusion of Tor's approach and mine.
