-Overview
-
-    This extension adds a new pixel storage parameter to indicate that

-    conventional bottom-to-top order.  Only pixel packing can be
-    inverted (i.e. for glReadPixels, glGetTexImage, glGetConvolutionFilter,
-    etc).
-
-    Almost all known image file formats store images in top-to-bottom
-    order.  As it is, OpenGL reads images from the frame buffer in
-    bottom-to-top order.  Thus, images usually have to be inverted before
-    writing them to a file with image I/O libraries.  This extension
-    allows images to be read such that inverting isn't needed.

-
-    Resolved:  No, we're only concerned with pixel packing.  There are other

-    zoom) or glTexImage (invert the vertex T coordinates).  It would be easy
-    enough to define a complementary extension for pixel packing in the
