gridpattern v1.0.1

Bug fixes and minor improvements

• guess_has_R4.1_features() can now also take advantage if dev.capabilities()
  explicitly indicates that a feature is not supported in active graphics device.
• To match aesthetic changes in {ggplot2} one may now use the parameter linewidth to
  set polygon/path line widths in
  grid.pattern_circle(), grid.pattern_crosshatch(), grid.pattern_pch(),
  grid.pattern_polygon_tiling(),
  grid.pattern_regular_polygon(), grid.pattern_stripe(), grid.pattern_rose(),
  grid.pattern_wave(), and grid.pattern_weave().
  For backwards compatibility one may continue to use size as well.
  Continue to use size (or gp) to set the fontsize in grid.pattern_text().
  Both pattern_linewidth and pattern_size will be available
  for use in custom patterns (#57).
