Title:
  Panoglview could detect identical tiles for memory savings

Status in OpenGL Panorama Viewer:
  Triaged

Bug description:
  The panos I shoot are rarely 360x180. The areas of the
image with no data are generally black.

PanoGLView program could save a lot of memory if it
detected areas of a single color and used the same
texture tile for the whole area.

What I mean is that the part of the program that
creates tiles for the 3D view could notice when a tile
is all one color, and save it as a "master tile" to be
re-used for other areas which are also that color. This
would work no matter what color was chosen for the
"unused" area of a partial panorama. It should save a
lot of main memory in the computer and texture memory
in the video card, which matters when you have a
panorama which is both high-rez and incomplete.
