Henrik Rydgård a7b1b319ce Limit PNG decode dimensions to prevent decompression bombs 
pngLoadPtr allocated the decoded buffer directly from attacker-controlled
PNG IHDR dimensions with no upper bound, so browsing a crafted game icon
or savedata could trigger a multi-gigabyte allocation.

- Add maxWidth/maxHeight parameters to pngLoadPtr (default 8192x8192)
  and reject images larger than the limits.
- Thread the limits through LoadTextureLevelsFromFileData,
  CreateTextureFromFileData, and CreateTextureFromFile.
- Limit game icons to 256x128 in GameInfoCache and IconCache.
