Add an image allocation pool to the OpenVG paint engine
Some OpenVG GPU's have limitations on the amount of memory
available to create VGImage's. When the memory runs out,
vgCreateImage() will fail.
This change introduces QVGImagePool, which keeps track of all
QVGPixmapData image allocations and ejects least-recently-used
pixmaps when GPU memory is exhausted.
