Character: type whose method would draw past the pixel budget is drawn as Sharp

Browse Source 
None, Crisp and Strong type is drawn offscreen on the output's pixels.
The offscreen drawing was limited to 32,768 pixels a side, but not in
area, so type across a large raster export held several more images of
the export's size. Type whose offscreen drawing would hold more than the
renderer's pixel budget (8.4 million pixels) is now drawn as Sharp draws
it.
