Patch v2

Thank you for your review.
I am not sure I can store the number of pixels to draw in a platform
independent way. For example, in the Qt port on different operating systems, we
have different border widths and different paddings for the different progress
bars.

In order to not lose precision, I replaced the previous 100 with 65536, I hope
this is good enough precision for all platforms.

This patch adds a method for getting the size of the dirty rect from the
platform, if available.
