* Considering large pixmap is not a normal case, to keep
* it simple, I designe it as the following way.
* When deal with a large pixmap, it split the working
* rectangle into serval boxes, and each box fit into a
* corresponding fbo. And then the rendering function will
* loop from the left-top box to the right-bottom box,
* each time, we will set current box and current fbo
* to the box and fbo elements. Thus the inner routines
* can handle it as normal, only the coords calculation need
* to aware of it's large pixmap.
*
* Currently, we haven't implemented the atlas pixmap.
