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.

b6c7c0d799 Optimise glyph lookup in text renderer
std::map lookup was a major cost when rendering large amounts of text.
Replace it with a more efficient 2-level array.

This was SVN commit r14017.

5778484a77 Refactor text renderer
Replace unifont with CFont and CFontManager, since the h_mgr interface
was
needlessly inconvenient.

Load the font textures through CTextureManager, to support dynamic
reloading (e.g. when resetting GL state - see #741).

Add CFontMetrics as a convenient wrapper for code that just wants to
measure text.

Fixes #1117.

This was SVN commit r14016.
