Fixed SetTextAlign(), SetBkMode(), SetROP2(), SetPolyFillMode(), and

SetStretchBltMode() to assume that the corresponding DC driver functions return only a BOOL success flag, and therefore a proper return value should be generated by the main function. Fixed EMFDRV_StretchDIBits() to return a proper value (like MFDRV_StretchDIBits already does). Added comments about other cases of improper return values.

Fixed SetTextAlign(), SetBkMode(), SetROP2(), SetPolyFillMode(), and
