2005/04/01 16:09:43 thb 1.5.2.1: #i36190#, #i39245# Changed uno::Sequence::operator[] for nonconst sequences to use naked ptr; added support for true bezier polygons (and removed subdivision, where it was added because of that canvas deficiency); overhauled mtf renderer to provide faithful bounds also for subsetted meta files
