artemp/trac2github — Issue #606: Faster, safer reprojection
Author: artemp

Something is not right in proj.4 land. Mapnik kept pace with MapServer in the recent WMS benchmarks for rendering in non re-projecting scenarios, but did not scale when on the fly reprojection was tested.

A bunch of speedups were found previously by removing some uneeded locking, but likely there is more that needs to be done.

See: r2063 and r2181 (backported to 0.7.2 - #575)
