Don't send any commands to the GPU while hidden

Browse Source 
Previously we weren't doing drawing, but we were enqueuing viewport commands and so forth, which were causing GPU permission errors on iOS. We really don't want to be sending any work to the GPU when we're in the background.

(cherry picked from commit 57f3d2ea0a)
