Parameters

h	The content to redraw
width	The target width
height	The target height
ctx	current redraw context

Returns: true if successful, false otherwise

The thumbnail is guaranteed to be filled to its width/height extents, so there is no need to render a solid background first.

Units for width and height are pixels.
