Ok, let me give you some 'criticisms' I have of parts of the
approaches to this filters stuff that both Carsten and Gustavo
suggested, and let me start with:
I just don't see a realistic "need" for having a built-in
mechanism of arbitrary lists of arbitrary filters to be applied
to any evas obj (or the rendering of such an obj), or as a canvas
modifier object itself.
I wish someone would point out an interesting, and/or common,
real-time gui use of something besides: one specialty filter (say a
blur or a bumpmap) followed by a geometric transform (and possibly
all clipped by a mask).
Anything more involved than that I'd say should be left to
immediate-mode mechanisms for people to compose things as they
wish (working with image objs), ie. draw the obj to an image obj
and proceed to work with such.. use whatever eventual im obj to
represent whatever bizarre, complex, slowly-arrived-at result you
wanted.. I doubt one'd be going thru these steps all the time,
so might as well create what complex effect you want and save it
as an image obj for your actual real-time use (and any animations
on this kind of thing you'd probably want to do apart from that,
ie. on that result).
