		Internationalized font and text drawing support.
	</brief_description>
	<description>
		Font contains a unicode compatible character set, as well as the ability to draw it with variable width, ascent, descent and kerning. For creating fonts from TTF files (or other font formats), see the editor support for fonts. TODO check wikipedia for graph of ascent/baseline/descent/height/etc.

				Draw "string" into a canvas item using the font at a given position, with "modulate" color, and optionally clipping the width. "position" specifies the baseline, not the top. To draw from the top, [i]ascent[/i] must be added to the Y axis.

			<description>
				Draw character "char" into a canvas item using the font at a given position, with "modulate" color, and optionally kerning if "next" is passed. clipping the width. "position" specifies the baseline, not the top. To draw from the top, [i]ascent[/i] must be added to the Y axis. The width used by the character is returned, making this function useful for drawing strings character by character.
