| public void renderImage(ImageData image, BaseTransform transform, FilterContext fctx) Renders the indicated ImageData to the output with the
indicated transform using BILINEAR filtering.
This method should only be used by an Effect if there is only
a single output or if there are multiple outputs which would have
otherwise been combined into a single output using the Porter-Duff
SrcOver composite mode.
If this method is used to render all image results of an effect
operation then the effect may return null as its output result.
This method should not save a reference to or modify the reference
count on the ImageData argument.
