Changes in this CL:
- CaptureCursor() scans the cursor to verify that it has alpha channel.
- The AND mask of the cursor is used to reconstruct transparency if the cursor does not have alpha channel.
- CaptureCursor() always outlines the cursor when a "screen reverse" pixel detected. Previously it was only done for black and while cursors.
Added desktop_capture_unittest.MouseCursorShapeTest to test the cursor conversion code.
