REGoth: ../src/gallium/auxiliary/util/u_blitter.c:2048:
util_blitter_generate_mipmap: Assertion `!util_format_has_stencil(desc)'

REGoth is a project reimplementing the game engine used for Gothic 1 and 2.
They use bgfx for rendering and the assert is caused by whatever that library
is doing. Its startup output is attached.

This may be an application bug, but commenting out that assert makes ReGoth
work with seemingly no ill effect, so it would be nice if it could be verified
that it's a valid assert and report it downstream to bgfx if it is.

Only tried with radeonsi latest git on RX 480 but the location of the assert
probably applies to all drivers.
