Fixes font glyph edge artifacts and scrolling

Adds X/Y 0.01 offset to the projection ortho.
Corrects font glyph edge artifacts as well as a 1px gap at the 
seams of tiled scrolling backgrounds as was observed by many
users of NVIDIA cards.  This was extensively tested by many
users of NVIDIA, AMD, INTEL, iGPU & onboard cards. This does not
have any adverse effects on anything else or for people who never
experienced any issues.
