Otherwise the vertex shader will see stale posFixup values.

It's unused, all states that have this as handler have a 0 representative.

wined3d: Only apply float R16G16F/R32G32F fixup when ARB_texture_rg isn't around and remove redundant code.

wined3d: Remove redundant gl format/type code from d3dfmt_get_conv since it is already in the table.

Some applications do not expect and could have undefined behaviour (or even
crash) when a not active (and disabled) main window under a dialog popup is

Windows doesn't.

ntdll: On x86_64 systems (as on i386 ones), hw breakpoints must generate a EXCEPTION_SINGLE_STEP exception.
