[All?] NVidia Nsight reports incomplete textures in use

[skyloutyr]

It seems that there is an incomplete texture in use somewhere but nsight isn't helpful in locating it, as it simply marks all draw invocations with the warning, and all textures it internally lists are complete according to it. May be an nsight bug, may be an actual incomplete gl texture somewhere.
Not a high priority right now as it doesn't seem to affect anything, but it may affect stricter drivers (on mac) or AMD, so investigation is still needed.

Since c8efba1 NSight no longer reports incomplete textures and textures seem to function fine for testers. Closing for now, reopen if there are unknown texture issues with specific hardware
