Re: ODF TC issue 2049 custom shape enhancement

Hi Regina,

Sorry that being late to reply about this topic. I've spend some time in
oox last year. I try to make built-in shapes export to ooxml as much as
possible. It might be a little wired, but my major concern about blending
to another color value is how reset of the filters can emulate the effect.
Currently users can group different shapes with different transparency.
That might be an alternative although there are still differences.

Best Regards.
