Lower-end override for [member rendering/quality/intended_usage/framebuffer_allocation] on mobile devices, due to performance concerns or driver support.

Enable usage of bicubic sampling in baked lightmaps. This results in smoother looking lighting at the expense of more bandwidth usage.
Enable usage of bicubic sampling in baked lightmaps. This results in smoother looking lighting at the expense of more bandwidth usage. On GLES2, changes to this setting will only be applied upon restarting the application.
