* Headers/cairo/XGCairoModernSurface.h:
* Headers/cairo/CairoSurface.h: New cairo surface which uses
cairo_surface_create_similar to create a back buffer which
has an alpha channel, even if the X server doesn't support
surfaces with alpha. This new surface is also made the default
since this seems to be the recommended way to double buffer
with cairo.

9b930f8ec7 * Source/cairo/CairoContext.m: Switch to XGCairoSurface by default, 
because it fixes the corrupted display problem reported by Riccardo
on 16-bit displays.

gstate.

faster drawing operation when the clip can be represented as a
list of rectangles.

clip rectangle list.

b53fe57e7c Fixed many drawing issues (many ones being related to the flipping). 
See bug report #27782

In particular, fixed -[NSImage drawXXX] and -[NSImage composite/dissolveXXX] 
methods to work exactly as Cocoa when the Cairo backend is used.
Added a new draw operator (in addition to composite) to the backend. Cairo is 
the only backend that implements it for now.
Eliminated as many flipping checks as possible.

Warning: Untested with the winlib backend. 
You must update, recompile and install both Back and Gui.
