When application exits the d3d pipeline is not released correctly, which
causes a large memory leak.

SUGGESTED FIX http://sa.sfbay.sun.com/projects/java2d_data/6u4/6592428.0

EVALUATION There are two methods in the D3DContext class for resource disposal: - to release default-pool resources only (ReleaseDefPoolResources()) - to release all resources (ReleaseContextResources()), inlcuding those in default pool ReleaseContextResources is supposed to release all resources including all default pool ones, but one resource (pSyncQuery) was missed, which resulted in d3d devices not being released, causing a leak. The fix is to call ReleaseDefPoolResources() from ReleaseContextResources() to make sure all default pool resources are released.
