When we need to solid fill an entire pixmap with a specific color, we do not need to draw it immediately. We can defer it to the following occasions: 1. The pixmap will be used as source, then we can just use a shader to instead of one copyarea. 2. The pixmap will be used as target, then we can do the filling just before drawing new pixel onto it. The filling and drawing will have the same target texture, we can save one time of fbo context switching. Actually, for the 2nd case, we have opportunity to further optimize it. We can just fill the untouched region. By applying this patch, the cairo-trace for the firefox-planet-gnome's rendering time decrease to 14seconds from 16 seconds.

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.
