Draws a textured rectangle region of the multi-channel signed distance field texture at a given position, optionally modulated by a color. See [member FontFile.multichannel_signed_distance_field] for more information and caveats about MSDF font rendering.
If [param outline] is positive, each alpha channel value of pixel in region is set to maximum value of true distance in the [param outline] radius.
