+/**
+ * Notes about the predefined gl_texture_formats:
+ *
+ * 1. There are 1D, 2D and 3D functions for fetching texels from texture
+ *    images, returning both GLchan values and GLfloat values.  (six
+ *    functions in total)
+ *    You don't have to provide both the GLchan and GLfloat functions;
+ *    just one or the other is OK.  Mesa will use an "adaptor" to convert
+ *    between GLchan/GLfloat when needed.
+ *    Since the adaptors have small performance penalty, we provide both
+ *    GLchan and GLfloat functions for some common formats like RGB, RGBA.
