enum wxStockCursor

Standard cursors.

Notice that under wxMSW some of these cursors are defined in `wx.rc` file and not by the system itself so you should include this file from your own resource file (possibly creating a trivial resource file just containing a single include line if you don't need it otherwise) to be able to use them.

See wxCursor.
