Allowing Compound Glyphs with `numberOfContours < -1` 
While it is recommended that the numberOfContours are set to -1 for compound glyphs, it is allowed to have any negative value. Source: https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6glyf.html

However, I don't know if this happens in practice.

Georgy Macharadze 4e0c494515 stb_image: fixed 'out' nulled but not freed upon failure 
If realloc fails it returns NULL and out pointer becomes invalid. To
fix this it is necessary to store realloc return value in temporary
pointer and then compare it with NULL. If it equals NULL then return
error and source pointer will still valid.

This error was caught by cppcheck:
Common realloc mistake: 'out' nulled but not freed upon failure.

Chris Young 0a1016331c Add functions to extract SVG glyphs from font. 
The fucntions are:
stbtt_GetCodepointSVG - provides a pointer to the SVG data in the supplied argument, and returns the length of this data
stbtt_GetGlyphSVG - As above but takes the glyph index instead of the codepoint
Note that the returned data may be deflate compressed.

rgriege 8ac257b00f stb_truetype: limit to 1 missing glyph in texture 
When calling stbtt_PackFontRanges, multiple missing glyphs in the range
of codepoints will create multiple copies of the font's missing glyph to
be added to the pixel buffer.  Instead, the first codepoint that maps to the missing glyph will add it to the pixel buffer, and all subsequent glyphs will simply copy the stbtt_packedchar data to reference the same region of the buffer.

This does NOT prevent duplication in multiple calls to stbtt_PackFontRange(s) - that would require modifying the packing context, which could be nice but is a bit more intrusive.

Sean Barrett b8960f32b8 stb_ds: major string hash fix, minor other changes 
- arena and strdup string hashes were badly broken due to not setting up default slot correctly
  - tweak use of seed in 4-byte and 8-byte hash functions to hopefully be slightly stronger
  - a few internal #ifdefs for performance tuning

Fabian Giesen 6570d6a825 stb_image: Make GIF reader validate image size. 
I must've missed it when I did this for the other image loaders.
Either way, combined with the previous checkin, this should fix
issue #614 properly.

Fabian Giesen 50b1bfba58 stb_image: Fix multiple bugs in GIF decoder. 
1. Check not just g->out allocation for failure.
2. If an image descriptor specified a 0-width image, this could be
   used to produce an out-of-bounds write.
3. Fix memory leak in case an error occurs during decoding.

Fixes issue #656.

Fabian Giesen ae431d75e0 stb_rect_pack: Fix two bugs. 
stbrp__skyline_find_best_pos didn't correctly handle rects too
large to ever fit inside the context. Since that function also
pads the width up to a multiple of the alignment, it makes the
most sense to do that check right after (but before entering
the main packing loop).

While we're here, also fix an off-by-1 bug in the best-fit
heuristic where it didn't want to use the last row in
certain cases.

Fixes issue #701.
