This is definitely a big deal for us (Freevo). We've been resorting to
ugly hacks to get this effect in text (i.e. using Imlib2 to render the
text to an evas image object and fiddling with the alpha channel after),
but other hacks are increasingly impractical for use-cases that involve
fading across multiple objects.
So I'm interested in hearing any advice from those who grok evas's core
(of which I am not even remotely one).
Off topic now, but some other shortcomings that are an issue for us:
1. Lack of 3D transformations (on 2D objects). Gustavo has said he
has a proposal for adding this, which is very nice to hear.
2. GL engine a second class citizen. I sometimes read on e-devel
about how this or that isn't working properly in the GL engine.
At some point configure was updated to no longer build it by
default. I'm afraid one day I'll do a svn update and discover
raster has removed it because it was half working and nobody cared
about it. [I care! :)]
3. Lack of subpixel precision. Makes stuff like the Ken Burns Effect
impossible (or possible, but lame). However this is probably not
practical without a big evas rewrite. I did just have the idea
that we could get halfpel by creating a canvas size twice the
display resolution and set the viewport to the display resolution
-- but that option won't work since viewport feature was removed.
Other options require buffer canvas hacks.
Anyway, thought I'd just mention this stuff so they're in the right
people's minds. :)
Jason.
