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.
When CTextRenderer is given multiple strings with no differences other
than position, render them in a single glDrawElements call to reduce
driver overhead.
Also avoid some unnecessary copies of std::wstrings.
This helps performance a bit with large GUI text boxes.
This was SVN commit r14018.
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.
Switch all the constant strings in graphics code to use the new
variables.
This avoids the cost of instantiating CStrInterns at runtime every
frame.
This was SVN commit r13906.
