Transformation caching during reprojection triangulation
...
This usually saves around 30-35% of transformation calls.

Alternative reprojection triangulation strategy
...
The quads are now subdivided more granually (to 2 instead of 4), which
usually leads to reduced number of triangles and higher performance.

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.

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.
