Comment 38 for bug 1241902

Hi to all.
This patch is because depend the type of live effect could be ok or wrong, apply this effect to clips and mask.

For example BEND and ENVELOPE, LATTICE... are effects give improved results with clips/mask
SKETCH, HATCHES... give wrong results.

With this patch you can active it in each effect.
For now is only applied to Bend LPE for testing.

To enable more effects, look arround line added to code in lpe-bendpath.cpp
TODO: Make a full list of effects handle well with LPE on clips/mask.

Regards, Jabier.
