Let's be careful with these statements here. Evas is not
a "bad choice" for loading renderable formats of some type..
wether SVG or whatnot.
One could imagine formats that are designed in such a way
that they require that you specify any number of things in order
to realize them as some set of pixels..
Assuming you had the means to actually render the format,
or just have something else render it, you would still need to know
what the types of attributes are, and then let the user have a
means of specifying them somehow.
Evas' current image loading api could actually handle most
anything via the use of the (file, key) pair.. it's just a matter
of wether or not to do it that way or some other way.
Loading 'SVG icons', at this point in time, really just
means rendering some static SVG doc at some scale and then using
that rendered image.. There are libs that can do that, the most
commonly used by some seems to be 'librsvg', which latest version
seems to use Cairo for the rendering (and various other libs as
well.. including glib and gdk I believe).
