import background

daz studio 4.15, blender 2.92, commit 514ecea

In relation to #473, commit 514ecea works great with the “always“ option. But I see we lost the background pictures that were imported fine in #129. Then while we’re at it, it would be nice to implement the rotation and flip settings. So we’d had a pretty complete import of the daz environment and background. Test scene included env-and-back-2.duf.

As for the options, if I understand them correctly, I’d suggest the following names that may make more sense to daz users.

1. environment and background
2. environment only
3. none

Then personally I don’t understand the “environment only” option since the background interacts with the environment in daz studio. For example when we don’t draw the dome and there’s a background visible in render. If the user doesn’t want the background then he can just turn it off in daz studio before exporting. But I understand this is my personal view and others may differ.

It is quite trivial but just in case it can be useful here it is the setup for the background image.

if rotate left 90 degrees
  rotation z = 90
if rotate right 90 degrees
  rotation z = -90
if rotate 180 degrees
  rotation z = 180
if flip vertical
  scale y = -1
if flip horizontal
  scale x = -1

Everything should work now, I think.

The “Dome” option is changed so it also creates a world if there is a background. So it only differs from the “Always” option if the environment mode is scene only and there is no background. In that case the “Always” option creates a transparent world, whereas “Dome” leaves the old world unchanged.

The option should have a better name, though.

Commit ad8fe22 works great. I still believe we can discard the options and keep only "always", so to have a "environment" checkbox as before.
