	* edje: Add Fixed Point Math support to Edje.

	You can try it by passing --enable-fixed-point to the configure. It
	will produce an ABI/API compatible Edje library that use internally
	Eina_F32p32 instead of double. It will load Eina_F32p32 instead of
	double from eet file (thanks to eet ability to convert them on the
	fly), so edje file are compatible between fixed point and floating
	point version.

	This patch touch almost all internal calc of Edje, I did test it with
	elementary_test, enlightenment and all my test apps, but it could
	certainly break some of your preferred Edje file. If you see any
	unexpected behaviour please report them to me as soon as possible.

	Note: For devs, I put few macros in edje_private.h that should now
	be used when doing calc in Edje, please use them so that Fixed Point
	doesn't break in the futur.
