Allows to store glyph advance also for notfound glyph, which is exactly
what we want for unknown characters. Also added version information to
allow further extensions.
We are providing already done font with parameters that GlyphCache can
handle. Moreover in ES DistanceFieldGlyphCache might expect RGB input
images because Luminance is not renderable in most cases, thus it
wouldn't work with Luminance TGA input.
The fonts is simply a file with character and glyph parameters
along with glyph cache image. There is also MagnumFontConverter, which
allows to create the font from any currently opened font.
Added tests for both, they both need active GL context due to GlyphCache
instance. MagnumFont doesn't have test for creating glyph cache yet.
