Description Brent Fulgham 2015-01-13 20:27:41 PST 
The following layout test is failing on Windows.

fast/css/crash-on-custom-cursor-when-loading.html

Probable cause:

Windows is refusing to create a DIB for the 'empty' icon during the initial load phase. This is returning a null value, which is then used in later API calls that assert that the arguments are non-null.

Solution is:
1. If the DIB cannot be created by the operating system based on the icon description, return a nullptr.
2. If the 'createSharedCursor' call returns nullptr, fall back to the default icon case so that we have something that can be used during early layout until the load finishes.
