GDK: Use GdkCursor objects to keep track of W32 cursors, not HCURSOR In particular this means that cursors are disposed of by the way of g_object_unref(), not DestroyCursor (which is documented to not to be used on certain kinds of cursors, and we can't tell which is which). It should also alleviate any concerns about destroying cursors that are still in use by other windows, except for cases where we would somehow get our hands on a HCURSOR that someone else is using and we make a GdkCursor out of it and later unref and finalize it while it is still in use. It also removes the need to call CopyCursor(), which makes animated cursors into non-animated ones as a side-effect (supposed to be a bug, but try explaining that to MS). Now cursors should be animated (if the are set up as such in the OS). https://bugzilla.gnome.org/show_bug.cgi?id=697477
