 				Draw character [code]char[/code] into a canvas item using the font at a given position, with [code]modulate[/code] color, and optionally kerning if [code]next[/code] is passed. clipping the width. [code]position[/code] 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.
+				If [code]outline[/code] is [code]true[/code], the outline of the character is drawn instead of the character itself.
