[Mesa-dev] Empty files when dumping hud values selected with GALLIUM_HUD

[Julien Isorce]

Thx Edmondo, let me know the result! Also is the pane on screen supposed to
work with llvmpipe driver because I cannot see it with GALLIUM_HUD=fps
LIBGL_ALWAYS_SOFTWARE=1 GALLIUM_DRIVER=llvmpipe glxgears

Cheers.
