forked from enlightenment/efl
added in loading froms from memory buffers at the engine level, and now an
api to set a font "source" (blank is normal filing system) but the source can be a device or file etc. in this case it currently supports eet files as the source and then the font name is used as a key in th eet file as to where to find the font - edb support would be trivial to add. :) if the font is not found in the "source" it falls back to the font path etc. SVN revision: 8625
