gridpattern v1.2.2

Bug fixes and minor improvements

• grid.pattern_weave() adds the new units parameter
  that most other "geometry" pattern functions received in gridpattern v1.2.1.

• The "polygon_tiling" pattern should now respect the units parameter
  if set to a value different from the "snpc" default (#82).

• For the "polygon_tiling" pattern type = "18.18.3*" the size of the
  eighteen-sided polygons have been increased a teeny bit and
  this polygon tiling should look a bit cleaner.

• The following "placeholder" pattern updates (#83):

  • The following placeholder pattern names are now serviced by lucidinternets.com:

    • "cage" and "cagebw"
    • "murray" and "murraybw"
    • "seagal" and "seagalbw"

  • The following placeholder pattern names have been removed since their associated web service no longer works:

    • "lorempixel" and "lorempixelbw" (service unavailable since 2022)
    • "placeimg" and "placeimgbw" (support officially ended July 2023)

  • The "dummybw" name now provides a pure black-and-white image (i.e. no grey).

  • Fixes a regression for the "placeholderbw" name where it redirected to the "seagal" name instead of "placeholder".
