Load alpha bitmap as a texture. It is internally converted to RGBA format
by OpenGL. This means a specialized shader will be needed for rendering
text, since the diffuse texture's RGB components will always be 0, while
alpha corresponds to the fill of the pixel.
Texture: Use RGBA format and GL_LINEAR magfilter
Add font test
Font: Use 512 instead of FSZ macro for tex size
Font: Change var identifier; it's a file path name
Font: Don't add C: to search path (was for debug)
