- Scroll the selected reference into view (makes it easier to tell which pdf you're looking at)
- Show the keyboard shortcuts (easier for new people)
- Keep the test/ref controls visible (if you scroll you can now tell if you're looking at a test or ref)
This will default to generating test images at the device pixel
ratio of the machine the tests are created on unless the
test explicitly defines and output scale using the
`outputScale` setting. This makes the test look visually
like they would on the machine they are running on. It
also allows us to test different output scales.
When reftest analyzer shows magnified pixels, there is a seemingly random offset between the mouse position and the magnified position. The reason for this is that reftest analyzer assumes all images have 800 * 1000 pixels but actually the test images have varying sizes.
