* Basic notes:
* 1. Want compact representations, so we use bitfields.
* 2. Put bitfields before other (GLfloat) fields.
+ * 3. enum bitfields need to be at least one bit extra in size so the most
+ * significant bit is zero. MSVC treats enums as signed so if the high
+ * bit is set, the value will be interpreted as a negative number.
+ * That causes trouble in various places.
