This is the first commit to add support for large pixmap. The large here means a pixmap is larger than the texutre's size limitation thus can't fit into one single texutre. The previous implementation will simply fallback to use a in memory pixmap to contain the large pixmap which is very slow in practice. The basic idea here is to use an array of texture to hold the large pixmap. And when we need to get a specific area of the pixmap, we just need to compute/clip the correct region and find the corresponding fbo. We need to implement some auxiliary routines to clip every rendering operations into small pieces which can fit into one texture. The complex part is the transformation/repeat/repeatReflect and repeat pad and their comination. We will support all of them step by step. This commit just add some necessary data structure to represent the large pixmap, and doesn't change any rendering process. This commit doesn't add real large pixmap support.

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.
