** This file contains routines that deal with unpacking data from client
** memory using the pixel store unpack modes and then shipping it to

** are two forms of the transport - small and large. Small commands are
** the commands that fit into the "rendering" transport buffer. Large
** commands are sent to the server in chunks by __glXSendLargeCommand.
**
** All of the commands send over a pixel header (see glxproto.h) which
** describes the pixel store modes that the server must use to properly
** handle the data. Any pixel store modes not done by the __glFillImage
** routine are passed on to the server.
