Improve numerical stability of reprojection
...
By shifting the source points before calculating the affine transform to
obtain values from similar ranges (inputs and outputs of the transform).

Reproject every image only once per triangle
...
If the triangle has to be shifted, determine if the image has to be rendered shifted or not.

More robust way of handling non-global projections
...
If the target projection has specified extent, it is respected.
Also adds various checks to optimize performance and/or
prevent potential errors.

Verify triangulation against source/target extents
...
If we do this here, we can avoid some computations on triangles that will
be unused in the future anyway + reduce problems with non-global projections
without specified extents.
