with 1.25 pixels_per_point text can become uneven:

The reason it gets like that is because I render each character as a textured quad. The font kerning requires a non-integral number of pixels of offset between characters. If I do that I get either blurry fonts (bilinear sampling) or weird offsets (round to nearest pixel).

Rounding to nearest pixel is done in Font::layout_single_row_fragment and in Tessellator::tessellate_text.

If we don't round to closest pixel, the text becomes even, but blurry:
