2da4b7a53d Disable DepthTest when drawing glyphs+move shared glyph draw logic
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.

2b71337c4a Remove one pixel offset 2022-07-07 15:38:06 +04:00
16bfe7f05b Use per-char width instead of fixed advance in font atlas
This gives us more (much?) efficient packing of letters
and we load exact size of the letters.

It looks visually a lot better too!
This wasn't good with normal smapling, but using texelFetch its
great.
