Ask and ye shall receive  ;) These images are all derived from a 360°x180° equirectangular panorama (my high res panorama test).

Your garden variety "light probe" (mask a circle to fit the square)

A tilted 180° fisheye image

Available projections with PTStitcher are rectilinear, cylindrical, fisheye and equirectangular.

To create my TG0.9 animation I ran TG via commandline with 6 TGS scripts (1 for each cube face), then stitched them to an equirectangular panorama, and then extracted an image with the camera heading/tilt angles at the desired projection/fov.  The same thing should be possible with TG2 once the CLI is fixed.

By keeping the equirectangular images, I could also extract a different camera angle from the same path which opens up a few extra editing options, not to mention editing zooms etc... without requiring a re-render.
