SVG equivalent transform tests.

These tests are for the algorithm 7.2. Computing the equivalent transform of an SVG viewport

The result on the left is rendered using the native SVG implementation. Each test consists of the following document structure:

• Outer svg element
• Inner svg element with various settings for viewBox and preserveAspectRatio. The viewBox coordinate space is green, the viewport space not covered by the viewBox is blue.
• a pink rectangle

The result on the right is rendered manually using the equivalent transform. Each test consists of the following document structure:

• Outer svg element
• a green rectangle with the dimensions of the viewBox from the inner svg element
• a pink rectangle with the equivalent transform

Note that the objects on the left are clipped to the viewports, while objects on the right are not clipped because the viewports are simulated.
