Improve reprojection performance
...
Utilize the numerical shifting during reprojection to easily reduce
complexity of the linear system that needs to be solved.

Optimize the reprojection by stitching the sources prior to rendering
...
This solves canvas antialiasing issues and also simplifies the code
handling wrapX in the source projection.

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.
