Tom Hacohen ff18fa8399 Evas: Multiple changes that all relate to the Harfbuzz integration:
1. Started feeding Evas_Text_Props to the font engine instead of Evas_BiDi_Props because no we have more general text properties as well - i.e, OpenType stuff.
2. Full Harfbuzz integration which gets compiled in by default (if harfbuzz is present) but only works if the environment variable EVAS_USE_OT is set to 1 (because OT is way slower than regular text rendering).
3. Cleaned the font querying/drawing functions.
4. Added font_shaped function to all of the engines, which by default calls teh harfbuzz stuff (default on linux that is).
5. Moved some source files around a bit to make more sense.

Tom Hacohen 99a7eff130 Evas bidi + font-engine + everything affected: Changed Evas_BiDi_Props to only include the direction of the text and reverse when needed. We don't need to do full processing at this stage, because we should have split to bidi runs before.

Tom Hacohen 6dba792f46 Evas font-engine: Change EVAS_FONT_WALK_TEXT_* functions to advance pen_x at the end of the loop (so a break won't advance it, but a clean finish will) and removed the checking if a diacritic using and advancement hack (that only worked only with specific fonts anyway) so we'll be able to start working with Harfbuzz.
