Stamp info back only for float buffer. (next commit add unsigned char).

A couple of new functions:
	BLF_width_and_height	- Merge of BLF_width and BLF_height in one call to avoid freetype2 stuff.
	BLF_buffer		- Set the buffer, size and number of channel.
	BLF_buffer_col		- Set the text color (the alpha is not used right now).
	BLF_draw_buffer		- Draw the text in the current buffer.

Also tweak a little the boundbox and draw function to avoid access the freetype2 and use the cache info.
By default the font size is 12, the UI still need work to allow change the font and size.
