Summary	06008: bfm_sc4.c: FATAL ERROR: Too many live textures in src/emu/renderer.c:500
Description	I know it's labeled as not working but the machines under BFM_ SC4 do work for the most part, all they are lacking is the payout hopper emulation and the 7segs need the 8bit data swaps sorting. However while working on a layout for it i stumbled upon a bug that causes the layout renderer (render.c) to stop working if too many bezel elements of varying sizes are placed, i believe the number is between 12 and 15 different sizes. But going back and changing the edited value allows the layout to run. You can see a video of me demonstrating the problem here - Tried the layout in various builds (32bit, MAMEUI, non self compiled versions) and the issue still persists.
Steps To Reproduce	Take default layout, edit and add 12 differently sized Bezel's, layout then refuses to load and render.c crashes the emulator.
Additional Information	The game does run and i am about 90% of the way of getting a functioning layout for it.

So, for example you have one named "blue_lamp", copy/paste that and name the copy "blue_lamp2" If that works, this bug can be closed.
