   …r=nical
   
   This makes the picture cache debug view more represent the amount
   of pixels that are being rasterized and composited. It's also a
   bit clearer where picture cache boundaries are on some pages.

   …h the primitive in WR r=gw
   
   Instead of trying to extract an inner rectangle from a transformed inner rectange,
   which by itself doesn't have an obviously "best" solution, we are going to test if the
   visibility rect is within the polygon of the projected inner rect.
   
   The test is more precise, could be slightly more heavy, but most importantly - it's correct.

   Turn the difference checkbox into a radio that adds "heatmap"; it uses
   WebGL to show both images, their absolute difference, and a color-coded
   max difference.  The quadrants split following the mouse.
   This helps to separate large variations (red) from small variations
   (green) and helps to compare the images without losing track of where
   they are.
