Hex Grid

This is a script to render hexagonal grids.

It shows up as Filters->Render->Pattern->Hex Grid... (which is the same sub-menu as the existing grid script).  This script works on the current layer/drawable to be consistent with the way the normal grid plugin works.

The options are:
Element to Specify - is either the length of one side, the
distance from point to point (equals the horizontal center to center in
a horizontal oriented hex grid) or side to side (equals the vertical
center to center in a horizontal oriented hex grid).
Length of Element - the length in pixels of the above item.
Hex Orientation - Horizontal or Vertical
Line width - the width of the stroke
Horizontal and Vertical offsets - when zero the first grid is
tight in the upper left hand corner, with the stroke half off the edge.
So for example, if you set it to a 1 pixel line width, you might want
to change the corresponding offset to 0.5 so the lines are drawn lined
up with the pixels and don't get aliased.
Color - colour of the hex grid, spelling the American way

Just a note that the grid dimensions and offsets are always to the
center of the lines, so if you run the script again with a different
colour and a thinner line width you can get some neat effects like the attached sample.
