INTEGRATION: CWS presfixes03 (1.6.2); FILE MERGED
2005/04/11 15:12:02 thb 1.6.2.3: #i36190# EffectTextArray/OutlineText wrongly rendered all subset glyphs on top of each other (did not pass offset calculated in createSubsetLayout() on) 2005/04/05 15:25:32 thb 1.6.2.2: #i39245# Fixed wrong output position of text in outline mode (this was due to the fact that the current map mode at the VirDev contained significant offset, temporarily removed that) 2005/04/01 16:09:45 thb 1.6.2.1: #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
