Draws character of \f(CW$cnumber\fR of \f(CW$font\fR. Also Unicode fonts are possible, if the font does provide that, just like next example:
.Sp
.Vb 2
\&        $font=new SWF::Font("Thai\-Bold.fdb");
\&        $sh\->drawGlyph($font, 0x0E44, 44);
.Ve
.ie n .IP "$shape\->drawCharacterBounds($character)" 4
.el .IP "\f(CW$shape\fR\->drawCharacterBounds($character)" 4
.IX Item "$shape->drawCharacterBounds($character)"
Draws an outer rectangle fitting for \f(CW$character\fR, an object of SWF::Character.
.ie n .IP "$shape\->setRenderHintingFlags(flags)" 4
.el .IP "\f(CW$shape\fR\->setRenderHintingFlags(flags)" 4
.IX Item "$shape->setRenderHintingFlags(flags)"
Set render hinting flags. Possible values are 
	SWF::Constants::SWF_SHAPE_USESCALINGSTROKES and
	SWF::Constants::SWF_SHAPE_USENONSCALINGSTROKES
.Sp
This method also will set version of this SWF::Shape object to 4.
