From 1f47388dfebf15f610993f046e1f945024c8fc3c Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Fri, 9 Jan 2009 18:28:38 -0800 Subject: [PATCH] Add language about implicit flush and command completion Copied language from the glXSwapBuffers manual page about the implicit glFlush and expected command completion. This just codifies what people already expect from glXCopySubBufferMESA. The intention of this command is to work like glXSwapBuffers but on a sub-rectangle of the drawable.
