Fabian Giesen f36b7116e2 Fix a few bugs with subpixel shifts, shift_y in particular. 
1. In the presence of nonzero shift_x / shift_y,
   stbtt_GetGlyphBitmapBoxSubpixel would return a nonzero-sized bounding
   box for empty glyphs (e.g. spaces). Since such glyphs don't have any
   outlines, the rasterizer wouldn't do anything, resulting in a 1x1-pixel
   image with uninitialized memory.
2. GetGlyphBitmapBoxSubpixel added shift_y then flipped the y axis,
   whereas the rasterizer flipped the y axis then added shift_y.
   Consistently flip-then-add in both places. This also makes the pattern
   of floors/ceils in GetGlyphBitmapBoxSubpixel simpler.
3. The rasterizer added shift_y after multiplying by the vertical
   oversampling factor, instead of before.

Vertical shifts now work much better, in my tests anyway.

Jorge Rodriguez a12d3dedf0 Some todo notes. 2014-09-16 10:50:41 -07:00
Jorge Rodriguez cbf5ebbd35 Install ryg's float -> uint8 sRGB conversion code, which is much faster. 2014-09-16 10:36:19 -07:00
Jorge Rodriguez 600d80387e Make a guess at the value before doing the binary search, cuts the number of conditionals by half. Not as much gain as I hoped but something. 2014-09-15 14:01:11 -07:00

Sean Barrett 9a6af9a8d3 replace int(floor()) with int(), since that produces same results for non-negative values and is much faster on 32-bit x86 2014-09-13 08:12:37 -07:00
Sean Barrett 1dcca19ae0 because of we divide by /255 not /256, we lose numerical precision, so can't guarantee that box filter results round to same results as naive 2014-09-13 08:06:39 -07:00
