+
+Performance issues with EXT_point_parameters & quake2
+
+
+
+Using glPolygonMode() where the front and back modes aren't the
+same causes poor performance on 3Dfx.
+
+
+
+Broken drivers: some of the Mesa device drivers (such as BeOS, D3D,
+etc) haven't been updated for Mesa 3.3's device driver changes.
+
+
+
+glDrawRangeElements() should use vertex array locking to improve performance
+but trying to do so causes a rendering error. Reported by Scott McMillan.
+Fixed by disabling locking in glDrawRangeElements (varray.c) but that's
+really just hiding a bug in array locking.

+ *
+ * The Mesa Main module consists of all the files in the main/ directory.
+ * Among the features of this module are:
+ * <UL>
+ * <LI> Structures to represent most GL state </LI>
+ * <LI> State set/get functions </LI>
+ * <LI> Display lists </LI>
+ * <LI> Texture unit, object and image handling </LI>
+ * <LI> Matrix and attribute stacks </LI>
+ * </UL>
+ *
+ * Other modules are responsible for API dispatch, vertex transformation,
+ * point/line/triangle setup, rasterization, vertex array caching,
+ * vertex/fragment programs/shaders, etc.
