=head1 NAME

Prima::sys::XQuartz - MacOSX/XQuartz facilities


XQuartz emulates X environment with certain limits, namely it cannot grab bits
from the screen, and it hides top-level menu from screen coordinates accessible
for X clients. For example, a Mac with 1024x768 resolution will only report
f.ex. 1024x746 size to Prima.  If Prima is compiled with Cocoa library,
C<get_fullscreen_image> method circumvents these limitations and returns shot
of the whole screen.
