d3d8/tests: Clear with colors that are more obviously different from the expected value in test_rcp_rsq().

oledb32: Add tests for DBTYPE_I1/DBTYPE_UI1/DBTYPE_UI2/DBTYPE_UI4/DBTYPE_I8/DBTYPE_UI8 to DBTYPE_WSTR/DBTYPE_STR conversion.

Add an identical SkipVariance function to make the code clearer.

widl: Add a type_memsize_and_alignment function to make it explicit where the alignment is truly needed.

Request method is determined by Wine on bind, so return success in this
function to make Gecko happy.
