This patch has identical rendering of the sample so the text does
render, and reduces code size and code duplication.

If bitmaps/backgrounds render but text does not then it's likely a
problem with the code that sets the region. All text/bitmap/fillrect
should  use the same clipping method (unfortunately, there is no
single clipping function and the code is duplicated so I cannot be
sure). If there is a real problem with clipping of text then it should
be fixed in fb.
