'remap only' option for GPLA objects

[zippy731]

GPLA does most of the work that VAMP does (edge and contour identification, occlusion testing, etc,) but GPLA results are always from camera view. Oscistudio needs the view to be top-down.

Create a Remap-Only option in VAMP that bypasses all of the VAMP calculations, and simply remaps the GPLA from the camera view to a top-down view, for consumption by Oscistudio.

Optionally, when in Remap Only, create multiple output objects from multiple GPLA inputs.
