VVVVVV/desktop_version/src/LocalizationStorage.cpp
Dav999-v ddaabb3efe Completely remove Graphics::bprint 
Only three deprecated functions remain:
- Graphics::Print
- Graphics::PrintWrap
- Graphics::bigprint

I also fixed multiline transparent textboxes having their outlines
overlap the text itself, and fixed textboxclass::padtowidth assuming
glyph widths of 8 (it made the hints at the start of intermission 1
run offscreen for example)
