StorePoints in glyph.cc guards the coordinate writes with
*offset + x_bytes + y_bytes > dst_size. On 32-bit platforms that sum wraps and can slip past the check, letting the following coordinate stores run past dst. The decoder's StorePoints already guards this; restructure to the same non-wrapping form used in the recent Buffer bounds-check fix.
