commit d6a1b7dcaeac1e49533519b9f8a279fd64d04c67
Author: Thomas Freitag <Thomas.Freitag at alfa.de>

    Some regression fixes/improvements
    
    I just finished the patch for these regressions, they had differents reasons
    1. In CharCodeToUnicode::mapToUnicode the identity support was missing
    2. The new algorithms for axial and radial shading caused problems in
    cairo. I revert these changes but removed the examination of hidden
    content (this is already done in the calling function)
    3. The examination of optional hidden content in showing text was wrong:
    of course hidden text should not be shown, but text parameters like text
    position in the state must be changed!
    4. Searching and finding fonts especially with base14 fonts should be
    more exact than just looking at the base14 name (i.e. fixed width and so
    on) when using fontconfig. I implement that to find the best font
    fitting to the needs.
