PixelPaint: Allow bigger Brush-Tool sizes

Browse source 
This patch allows a bigger brush tool size of 250 pixels and limits the
cursor bitmap to a reasonable size so that its not much bigger than the
image editor size. If the cursor is bigger as the editor it is rended
with a red edge to indicate that the actual cursor is bigger than
displayed. This change mitigates the OOM conditions when the cursor
gets unusual big.
