raster image of filters-morph-01-f

Test which verifies the basic facilities of feMorphology.

The test shows the same graphics filtered with four different feMorphology settings. The top two have the type erode and a radius of 1(left) and 2(right). The bottom two have the type dilate and a radius of 1(left) and 3(right).

The rendered picture should match the reference image, except for possible variations in the labelling text (per CSS2 rules).
