source: code/branches/cegui0.8_ogre1.9/data/gui/scripts/GUITools.lua @ 12035

Last change on this file since 12035 was 11809, checked in by landauf, 7 years ago

added work around for a bug in cegui 0.8 (the cegui lua scripts expect a "Font*" pointer to call getTextExtent(), but cegui 0.8 only returns "const Font*")
