From 8e3b658b7fdc1c2a2b9b6bd942a811adbf1ac4ab Mon Sep 17 00:00:00 2001 From: nobled Date: Mon, 30 Aug 2010 20:23:54 +0000 Subject: st/dri: Add multi-api support Make st/dri screens capable of creating OpenGL ES and OpenGL ES2 contexts. TODO: Figure out the "get_current" problem with multiple st_api's for real.
