Misa 70357a65bf Fix regression: Warp BG lerps in reverse direction
This fixes a regression caused by PR #923 (the PR that moved rendering
to be GPU-based) where the interpolation of the horizontal and vertical
warp backgrounds (in over-30-FPS mode) was in the wrong direction, which
makes them look blurry.

This happens because the arguments to the `lerp` function were in the
wrong, reverse order.

On the VVVVVV Discord server, Ally raised the argument that they were in
the same order before she made the changes; therefore the previous code
was also incorrect and it wasn't her fault. However, this argument is
incorrect, because in that case, the reverse order _is_ the correct
order.

The reason that it's now the wrong order is because the output of `lerp`
is now being used as the argument to a source rectangle. Previously, the
output of `lerp` was being used as the offset argument to
`ScrollSurface`, which is analogous to being a destination rectangle.

Fixes #1038.
