For some reason, SetDefExp2 type fog doesn't seem to work upon export, but regular SetDefExp does. This is just a proposed minor change to use the regular SetDefExp option if fixing the other is too big a task.
Plasma game installs are a per-user config item and should not be stored
in a blend file. Considering that we will be adding more per-user
configs, namely Python 2.[2|3|7] install directories, it seems like a
good move to go ahead and move the games over.
This makes sense because the pages to export checkboxes are here. The
export modal should be sort of a "last-chance" settings thing... not
actual core settings.
This is done using the new checkboxes on the page list under the World
panel. Seemed like the best way to do it within our format. Perhaps the
rest of the exporter options should move to that panel at some point.
It's important to not block a change if you're equal to yourself because,
in general, you're equal to yourself. I'm sure there are some edge cases
in that generalization though.
We are attempting to encourage the pages=layers paradigm; however, this is
not strictly enforced. This commit has lots of bits and bobs but little
actual substance. More to come when I begin work on the exporter.
