This tests feDisplacementMap without feImage. The input geometry is also used as the displacement map.

The bottom subtest tests that not specifying the 'xChannelSelector' attribute has the same effect as if 'A' was specified.

In both cases the filter input image consists of a gradient that is rendered using the default 'color-interpolation' which is 'sRGB'. The default colorspace for filter primitives is 'linearRGB'. The filtering operation happens in 'linearRGB' space and the result is then transformed back to 'sRGB' space for display.

Run the test. No interaction required.

The test has passed if:

the top rectangle is overlapped by a gradient that has its blackest part centered around the vertical green line that splits the top rectangle
the bottom right corner of the area covered by the top gradient is aligned with the corner just below the top rectangle
the bottom rectangle is overlapped by a gradient that is displaced upwards with the maximum displacement the middle indicated by the vertical green line that splits the bottom rectangle
no part of the bottom gradient extends outside the bottom rectangle
both gradients use the same gradientcolors
