draw() goes through all the phases of drawing, while renderSubTreeToImage draws
only the PaintPhaseForeground phase.
And like you said, renderSubTreeToImage is used for patterns and filter
effects.

Ifis the area to is draw smaller than the size of the svg, we wold call draw(),
not renderSubTreeToImage(), so I thought we should solve this bug by calling
draw() also in the case that the SVG is smaller than the area it should cover.
Please see Image:drawTiled().
thanks.
