Author: Brian Paul <[email protected]> Date: Mon Jan 28 11:32:13 2013 -0700 st/mesa: only enable GL_EXT_framebuffer_multisample if GL_MAX_SAMPLES >= 2 We never really have multisampling with one sample per pixel. See also http://bugs.freedesktop.org/show_bug.cgi?id=59873 Note: This is a candidate for the 9.0 branch.
