Zhigang Gong c6ce44d881 render: Enable more componentAlpha support.
Actually only PictOpAtop,PictOpAtopReverse and PictOpXor
can't be implemented by using single source blending.
All the other can be easily support. Slightly change
the code to support them. Consider those three Ops
are not frequenly used in real application. We simply
fallback them currently.

PictOpAtop: 		s*mask*dst.a + (1 - s.a*mask)*dst
PictOpAtopReverse: 	s*mask*(1 - dst.a) + dst *s.a*mask
PictOpXor:		s*mask*(1 - dst.a) + dst * (1 - s.a*mask)

The two oprands in the above three ops are all reated to dst and
the blend factors are not constant (0 or 1), it's hardly to
convert it to single source blend.

Now, the rendercheck is runing more smoothly.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
