fix: Port upstream 1.1.0-rc fixes (glyph null-safety, PNGdec wide image buffer)

Browse Source 
Cherry-pick two bug fixes from upstream PR #992:

- fix(GfxRenderer): Null-safety in getSpaceWidth/getTextAdvanceX to
  prevent Load access fault when bold/italic font variants lack certain
  glyphs (upstream 3e2c518)
- fix(PNGdec): Increase PNG_MAX_BUFFERED_PIXELS to 16416 for 2048px
  wide images and add pre-decode buffer overflow guard (upstream b8e743e)
