Make the glyphs in the Font class accessible

[prosd]

Hello,

First a kind thank you for making this great library available to the world!

Can you consider making the Font glyphs accessible from outside the Font class? For example by moving the 'FindGlyph' function from private to the public, or even protected, section of the class. I would like to get access to the font glyphs to draw rotated charatecters / text.

Thanks for considering!
