   7      Test related to bug 421780; make sure that 1-pixel, single-colour images
   8      are correctly scaled to the right size.
   9
  10      This test makes sure that images aren't sized too big; it takes a 100%
  11      width lime rect, overlaid with a 183x183 width stretched red image,
  12      overlaid with a 183x183 lime rect.
  13
  14      183 in particular is used because 183*183 > 2^16, and we can easily run
  15      into double-scaling bugs that will overflow in pixman.
