Subject: [PATCH] fix for increasingly slower addition of gfx ent (BZDNG-269)
when adding a gfx entity to the scene using scene.Add(), the time it
takes to add it is growing quadratically with the number of entities in
the scene (only in gui mode), which is caused by resizing of the table
in the sequence viewer.
