--- Comment #17 from Armin Le Grand <Armin.Le.Grand at me.com> ---
Made a short check what's going on. Generic sys-dep renderers would be ideal
(and were always the target after cont'ing the changes) but would not help too
much here.
The PatternFillPrimitive2D already does a decent, discrete (res- and target
dependent) buffered decomposition. Did that once for a similar case - the
pattern is tran'd to a bitmap and embedded in a stack of matrices to reflect
the fill (done based on discrete pixel size of pattern back-transformed to have
no gaps in pattern :) important).
In this case the range and size of the pattern derived/imported from the SVG
lead to creation of 2mio sub-primitives - argh! Either there is an error in
this file or we need to limit amount of decomp parts anyways due to mem overrun
attacks...
Just my 2ct
