WDDM Blt

This automated test is a stability test for the user-mode Device Driver Interface (DDI) for bit-block transfer (bitblt).

The test performs surface bitblts between a variety of surface types and memory pools. Longhorn Display Driver Model (LDDM) drivers must not crash in user mode or kernel mode during the test.
