For completeness there is now a new "fill" pattern with corresponding
grid.pattern_fill() which draws a simple fill pattern.
For completeness there is now a grid.pattern_none() corresponding to the previously
supported "none" pattern which draws nothing.
The default type for the "placeholder" pattern
is now "bear" instead of "kitten".
Explicitly set type = "kitten" to continue to use
the "kitten" placeholder but note that although
the "kitten" placeholder website isn't completely down
it has been buggy recently.
