# Graphical Grid

The unit at [gr/grid.fs] implements [io/grid] on a [gr/buf] by drawing cells
as [gr/font] glyphs.

Its color palette follows the VGA default palette.

This unit basically have one relevant word, "grgrid$ ( font -- )". This
initializes the grid and sets it as the active Grid. Example initialization:

  needs gr/font/uf1 io/prompt gr/grid
  "data/font/atari8.uf1" loaduf1 grgrid$
  ' gridrtype console!
  :> pos cursor! key ; prompt$
