[PATCH v2 0/4] MR10874: d3d8: Do not support multisampling for 16-bit formats.

[Conor McCarthy (＠cmccarthy)]

Star Wars Starfighter depends upon `Reset()` failing when it tries to enable multisampling, because it calls `LockRect()` on the back buffer, leaving it in WINED3D_LOCATION_SYSMEM which later hits "Not supported for multisample textures" in `wined3d_texture_gl_upload_data()`.
