[woff2] Support overlap flag for simple glyphs

System Internals / FreeType - Ben Wagner [chromium.org] - 20 March 2022 07:27 UTC

In the woff2 spec it has been proposed to allow the OVERLAP_SIMPLE flag to be retained through the woff2 format [0].

- src/sfnt/sfwoff2.h (GLYF_OVERLAP_SIMPLE): add glyf flag.

- src/sfnt/sfwoff2.c (reconstruct_glyf): parse optionFlags and overlapSimpleBitmap[]. (store_points): set OVERLAP_SIMPLE on first point's flag if the overlap bit is set.
