REVISION SUMMARY
  The old logic results in broken rendering if the sample was bigger than the
  area to render, due to normalized texture rect being 0 in the respective
  dimansion. As well as stretched mapping of the sample for fractional
  relationships between the area to render and the sample size.

TEST PLAN
  Borders of backgrounds of FluffyBunny theme render properly, no other
  regressions seen (but unsure what else might rely on that artifact).

REPOSITORY
  R242 Plasma Framework (Library)
