[PATCH v3 0/2] MR6300: Draft: wined3d: Don't reject cross-device blits.

[Aida Jonikienė (＠DodoGTA)]

I'm not sure this is 100% safe (maybe limiting those blits to sysmem textures
would be better like stated in the original change?)

[PATCH v3 1/2] wined3d: Don't reject cross-device blits.

[Aida Jonikienė]

From: Aida Jonikienė

This is basically a revert of commit db6f95880c2631b64e48adc547d365e878ae45a6.

Testing of the problematic game in bug 45382 shows it no longer crashes with those
blits enabled (even with CSMT) so I think this isn't a major issue anymore (and
rejecting cross-device blits can break some games like GTA 2 where the menu is
missing some textures after exiting from the game to the menu screen).
