Ykkrosh 91169c82c7 Optimise rendering of scrollable text boxes by clipping 
Add optional clipping rectangle to CTextRenderer. Strings that are
printed
outside the vertical extent of the clipping rectangle will be
immediately
skipped. This greatly reduces the cost of large scrollable text boxes.

This was SVN commit r14019.
