base.saveCubeMap is broken more then in 1.5.4

[Treeform]

base.saveCubeMap would break if other buffers where running in 1.5.4 range
but in 1.6.0 cvs head it competently messes up the and cases tons of errors to come from

and then every frame after:

Could you provide some sample code?

Okay, I've traced it down to these lines in panda/src/glstuff/glGraphicsBuffer_src.cxx :
        if (get_rtm_mode(i) != RTM_bind_or_copy) {
          continue;
        }
Uncomment them to make it work. For some reason, it doesn't want to do anything when the mode isn't RTM_bind_or_copy.
I don't have a clue what RTM_bind_or_copy is, I gotta check that before I can safely disable this.

Fixed.
