Disable DepthTest when drawing glyphs+move shared glyph draw logic

Browse Source 
With depth testing enabled nearby glyphs can z-fight
and so some pixels might be discarded before fragment shader
even runs, which causes us to see only part of a letter.

As such we always draw with blending enabled and depth testing
disabled so that any overlaps simply causes the char pixels to show.
