Fix memory leak from Font
FreeType’s FT_Glyph_To_Bitmap mutates the FT_Glyph by allocating a new
glyph object and overwriting the input pointer. This creates a risk of
memory leaks if the old glyph isn’t released or if ownership is unclear.

To avoid this, we now store the glyph in a UniqueFTGlyph and explicitly
pass it by reference to FT_Glyph_To_Bitmap. After the mutation,
ownership continues to reside in the smart pointer, and cleanup is
guaranteed even in error branches.

For temporary glyphs (e.g., strokes), we still manually call
FT_Done_Glyph, since they are not managed by UniqueFTGlyph. These
changes ensure all glyph memory is correctly released and reduce the
need for repetitive error-path cleanup code.

Use freetype for font rendering
Replace premade bitmap fonts with FreeType2 and dynamic texture atlas.

Switched from static, premade bitmap fonts to runtime-generated glyphs using FreeType2.
Glyphs are rendered on demand into a dynamic texture atlas, improving scalability,
font quality, and support for internationalization.

Currently using RGBA format for compatibility across all render
paths while initial support for R8_UNORM is being added.
This prepares for future optimizations in VRAM and performance

Includes groundwork for gamma-corrected blending and future swizzling support.

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.
