Image* ImageBuffer::imageForRendering()

This method returns an image that can be used for rendering right now (i.e the
QPixmap backing our canvas rendering context.) This lets us avoid the QPixmap
copy due to a painter always being active.

For all other ports, it simply returns ImageBuffer::image();
