Does this ever fail?  Do we check the error if it does?  Could this be the ctor
instead?

[dsinclair, 2016/03/16 19:59:16]

Done.

Are some of these cases unused now that the type can't differ?

Apparently m_rectInfo was never used, and we don't need m_bitmapInfo anymore.
Removed the union and just left the m_hatchInfo struct.

+      CFX_RectF rect;
+      FX_FLOAT xStep;
+      FX_FLOAT yStep;
+      FX_BOOL isColored;
