On one hand, it's my opinion that if I say no to is_format_supported for RENDER_TARGETs (or SAMPLERs, for copying), then the state tracker is misbehaving if it proceeds to request surface_fill or surface_copy with those. On the other hand, this fallback is kind of okay with me because it goes right next to the fallbacks for overlapping blits, which aren't okay on the 3D engine. On the *other* other hand, it'd be really nice if we had PIPE_CAP_BLITTER, which encapsulated all of this. ~ C. ------------------------------------------------------------------------------ Come build with us!
