[PATCH 4/4] dwmapi: add test for Dwmp{Get,Set}ColorizationParameters

[Louis Lenders]

Tests for Dwmp{Get,Set}ColorizationParameters, I could verify that the
first parameter is color RGB, and the 5th an 7th give a ``blur behind
window`` and opacity effect. As for the others: i guess one have to have
a trained/artistic eye to see the effects.
