Cherry-pick upstream commit 07d715e which refactors renderChar and
drawTextRotated90CW into a template-based renderCharImpl, hoisting
the is2Bit branch outside inner pixel loops for 15-23% speedup.
Additionally extends the template with Rotated90CCW to fix two bugs
in the mod's drawTextRotated90CCW: operator precedence in bmpVal
calculation and missing compressed font support via getGlyphBitmap.
