Michael Stahl 0c120f9dd4 cairo canvas: handle 8-bit grey-scale alpha colors: Apparently BitmapReadAccess::ImplCreate creates non-indexed color palettes in case of grey-scale, which leads to one assertion from BitmapColor::GetIndex() per pixel if that is accessed incorrectly; handle this better in cairo canvas.

README

UNO-based graphics backend, lesser impedance to modern graphics APIs
than vcl.

== The Canvas Framework ==

The canvas framework is the successor of the system GUI and graphics
backend VCL. Basic functionality is available, supplying just as much
features as necessary to provide a VCL-equivalent feature set (except
proper BiDi/CTL support).

The canvas framework consists of the following two modules, canvas and
cppcanvas. Additionally, a new generic graphics tooling is used (but
not exclusively by the canvas, Armin's drawinglayer module also make
use of it), which resides in basegfx.

The UNO API used by the canvas is primarily under
com::sun::star::rendering, with com::sun::star::rendering::XCanvas
being the central interface.

== The slideshow engine ==

The slideshow engine has replaced the former Impress-embedded
presentation framework with a fully independent UNO component, and it
is based on the canvas. Some features used there are only available
from canvas, like double-buffering, and hardware-accelerated
alpha-blending (currently not on all platforms).
