* Fixed a regression from 188.8.131.52 that caused instabilities in vnc connections.
* Added a preliminary option useGetImage to change from
memcpy'ing framebuffer regions to using the Xservers
NOTE: This option currently doesn't work with all encodings,
and currently only works with TranslateNone. e.g. the same
bits per pixel on the viewer and Xserver. It also requires!!! the
use of locally managed cursors. But the benefit is that some
older graphics cards don't like accessing the framebuffer while
the accelerator engine is working. This alleviates that problem.
