Craig Donner ee6978cb68 Slightly modify the public domain license to keep it in the public domain, but make it clear that even when dedications might not be recognized that the code is still usable. Given that this isn't dual-licensing under a different license, I'm hoping this will be acceptable. 2016-02-25 12:55:44 -08:00
Simon Glass 4ef7d07a44 ttf: Correct direct use of fabs() 
Add a macro to allow fabs() to be provided by the user, as with the other
maths functions. Update the implementation code to use it instead of fasb().

Sean Barrett 20b04f4aa9 stb_truetype version 1.06 
- switch from qsort() to built-in quicksort (about 2x as fast a sort, ~10% faster overall)
- use pool allocator for active-edge allocations (~10% faster overall)
- use new rasterizer (about 30% faster, ~10% faster overall)

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.
