* 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.

0, temporarily set it to 1 unit wide (in device space.) This
is an attempt at matching the behaviour of the setlinewidth
PostScript operator, which is supposed to interpret 0 as meaning
the thinnest line that the output device can draw.
Note that Quartz (and cairo) draw nothing with a line width of 0.

Add a new interface, GSShowGlyphsWithAdvances, which replaces
GSShowGlyphs as the primitive text drawing method.
None of the backends implement it properly yet; I simply renamed
the existing -GSShowGlyphs:: methods to -GSShowGlyphsWithAdvances:::,
so they currently ignore the glyph advances.

* Source/cairo/CairoFaceInfo (-characterSet): Remove the call to
FcFontMatch in -characterSet which was a big performace
bottleneck.
Instead load the character set data when enumerating all fonts in
CairoFontEnumerator.

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.

cairo_pattern_set_extend() on cairo > 1.6.0.

-DPSsetflat: and -DPScurrentflat should not have been transforming
the flatness value with the current transformation matrix.
The effect of this could be seen in the Apple BezierPathLab example;
zooming in on the circle caused it to look more and more like a
polygon.
Also set NSBezierPath default flatness to 0.6 to match OS X
(it was 1.0, which made circles look a bit rough)

font, as Bitstream Vera and FreeSans are no longer supplied
directly by Debian.

Adjust y coordinate of point in compositeGState:... for cairo. This
