pgeFont bitmap font library

[wraggster]

News/release from insert witty name:

pgeFont is part of Phoenix Game Engine.

-=Info=-
The library loads a TrueType font and generates a swizzled 4-bit paletted bitmap font texture for use when drawing text. It's very fast.

-=Samples=-
There are two samples included, one for raw GU and the other using the graphics library from Yeldarb's tutorials on psp-programming.com
If you're using the graphics library then you may need to reset the sceGuTex* states to what they are defaulted to in the initGraphics() functions, after using the pgeFont* functions.
It should be easy enough to add to any other library.

-=Dependencies=-
Freetype

-=Differences=-
The differences between this release and the actual Phoenix Game Engine pgeFont code are:
- No loading to VRAM
- No loading from memory

Possibly more on release of the engine.

-=Credits=-
Raphael: Converted my initial 8-bit textures to 4-bit and fixed a bug in the swizzle function.

Found a bug in a function:

int pgeFontMeasureText(pgeFont *font, const char *text)
{
if(!font)
return 0;

int x = 0;

while(*text)
{
Glyph *glyph = font->glyph + font->map[*text & 0xff];
x += glyph->advance;
+
+ text++;
+
}

return x;
}
