From 794cbd5800a4428babc100528fd4fdba49557b6f Mon Sep 17 00:00:00 2001 From: Tom Cooksey Date: Thu, 15 Apr 2010 12:48:56 +0200 Subject: Wrap EGL image function pointers and move into QEgl namespace QtGui exporting a symbol called eglCreateImageKHR seems a pretty silly idea. Much better to have them in the QEgl namespace.
