The following changes have been made to this directory since R3 (for
a full description, see doc/Server/r4.tbl.ms):
o Windows restructured (memory reduction, devPrivates and speedups)
o GCs restructured (memory reduction, devPrivates and wrappers)
o Screens restructured (window ops merged in, devPrivates)
o Pixmaps restructured (drawable changes mostly)
o Cursors restructured (shares glyph bits now)
o Visuals restructured (screen index removed, fields rearranged)
o Devices restructured (input extension changes)
o Out of memory changes. Many interfaces now return OutOfMemory
status.
o Synchronous grab code rewritten. Should conform to our
understanding of the protocol now. Be careful when time
stamping events (don't allow time to run backwards).
o Resource types redesigned and rewritten.
o Internal fake color allocation routine for software cursors.
