#14 Check necessity of `msabi_ID2D1DeviceContextGetUnitMode`

[Ruslan Garipov]

I believe msabi_ID2D1DeviceContextGetUnitMode is not required as a wrapper because ID2D1DeviceContext::GetUnitMode returns D2D1_UNIT_MODE which is an enumeration (thus, is not an aggregate).

So, we need to check if ID2D1DeviceContext::GetUnitMode causes segmentation fault in GCC binaries.
