From bfa66bd6f941920cf32ce79fb103c3755b4dd8fb Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Mon, 21 Sep 2009 17:57:57 +0800 Subject: mesa/es: Add OpenGL ES overlay. This is primitive support for OpenGL ES. It uses a subset of mesa sources to build libesXgallium.a and libesXapi.a, where X is 1 for OpenGL ES 1.x, 2 for OpenGL ES 2.x. The static libraries serve the same purpose as libmesagallium.a and libglapi.a do for OpenGL. This is based on the work of opengl-es branch.
