+ * 1. There are 1D, 2D and 3D functions for fetching texels from texture
+ * images, returning both GLchan values and GLfloat values. (six

+ * 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
