Verify the conversion processing of percentage and fraction values relative to object bounding boxes. This is used when defining linear and radial gradients.

The test validates conversion for coordinates, width, height and length. The first test defines two corresponding linear gradients, which specify coordinates using fractions for the first and user coordinates for the second. The second test defines two corresponding radial gradients, which specify a length (radius) using fractions for the first and user space for the second.

The rendered image should match the reference image.

The test also assumes that linear and radial gradients are implemented.
