Set of cursor resources available for use. These cursors come
in a sequence of values that are needed as the arguments for
pygame.mouse.set_cursor(). to dereference the sequence in place
and create the cursor in one step, call like this;
pygame.mouse.set_cursor(*pygame.cursors.arrow).
Here is a list of available cursors; arrow, diamond, ball,
broken_x, tri_left, tri_right
There is also a sample string cursor named 'thickarrow_strings'.
The compile() function can convert these string cursors into cursor byte data.
