This updates us beyond the version that is packaged in Ubuntu 24.04, which is freetype 2.13.2. Can you explain why you want to do this update?

I am trying to make a highly performant and reliable version of rviz.
I currently use mesh >2 Gb in real time simulation environments.
In addition to modifying ogre (I submitted an intermediate patch that does not impact the ros #1305 ecosystem), I also modified the freetype version for the following reasons:

  • Rare double-free crashes in the cache subsystem have been fixed.
  • Excessive stack allocation in the autohinter has been fixed.
  • The B/W rendering speed has increased and even doubled for very complex glyphs.

-DFT_DISABLE_ZLIB:BOOL=ON
-DFT_DISABLE_BZIP2:BOOL=ON
