Actually evas could easily draw vertical (ie. top-bottom)
text quite easily, as this merely requires advancing the 'pen'
by each glyph's advance in both x and y components (same for
kerning deltas) - right now it only advances the x coordinate.
I haven't looked at ft2 (last ft I looked at was ft1), but it's
likely that if the font is meant to be drawn vertically then
ft2 will give the required glyph y advances..
In any event, font/text issues are most definately a *huge*
pain, and it would require some time looking into ft2 and such
in order to get a good idea of what's involved..
But for things like html, rich-text, plain-text, funky-text,
etc, ... formatting schemes, it should be possible (and likely
preferable) to achieve such formatting schemes with external
'smart-libs' and some modifications to evas' core glyph drawing
(and possibly font/glyph caching).
