DSY is not that easy because we have to deal with the inverted coordinate
system in onscreen(!) rendering - see GLSL dsy.

d3d9/tests: Add simple test to show that QualityLevels is not zero, when we call CheckDeviceMultiSampleType with D3DMULTISAMPLE_NONE.

In D3D10 shaders input/output semantics are strings rather than predefined
types. Unfortunately, the code in vshader_get_input() can be performance
critical, depending on application behaviour. Since vshader_get_input() is
only relevant for d3d9 shaders anyway, just store the usage and usage_idx for
these shaders.

comctl32/listview: LVM_GETITEMRECT: don't offset to item position on LVS_REPORT querying LVIR_BOUNDS.

kernel32: Remove the file parameter check again in LoadLibraryExW since some broken apps pass garbage here.

Free the corresponding memory when the library is unloaded.

riched20: RTF{G,S}et{In,Out}putName() are unused so remove them as well as the corresponding _RTF_Info fields.
