This option controls the use of GPU acceleration and placement of auxiliary
buffers in memory. Enabling the Shadow will disable all use of the GPU for
RENDER acceleration and force software-fallbacks for all but updating the
scan-out buffer. Hardware overlay is still supported so Xv will continue to
playback videos using the GPU, but GL will be forced to use software
rasterisation as well. This is a last resort measure for systems with
crippling bugs, such as early 8xx chipsets. It is still hoped that we will
find a workaround to enable as much hardware acceleration on those
architectures as is possible, but until then, using a shadow buffer should
maintain system stability.
