Summary: X server backing store is assumed when not the case

Initial Comment:
The source module xwin.c  contains the following code
fragment ...

        if (DoesBackingStore(g_screen) != Always)
                  g_ownbackstore = True;

The intention being that redsktop will provide its own
backing store if the X server won't.

However,  just because the X server reports that it
will "always" do backing-store doesn't mean that it
will be available for all applications - backing store
might be resource capped.

X applications MUST ALWAYS be able to repint their
display - they cannot assume that the backing store
will eliminate the need for this.

I believe that the test is superfluous and that, at the
very least,  the variable "g_ownbackstore" must always
be TRUE - a complete solution requires the removal of
all references to the variable.

Many thanks for a superb product
