## cs-pixmap.api "cs" == "client-side"
#
# A client-side rectangular array of pixels.
# X jargon calls it an "Ximage" but I prefer
# a name more obviously related to pixmaps.
#
# Support for copying back and forth between
# client-side and server-side pixmaps makes
# them useful for specifying icons, tiling
# patterns and other client-originated image
# data intended for X display.

# The outer list corresponds to the list of planes, with plane 0 being

# Multiple planes are not very useful right now, as the pixel type is
# opaque. It seemed reasonable, however, to allow make_clientside_pixmap_from_readwrite_pixmap
# to work on all pixmaps, and the necessary changes were minimal.
