# Framebuffer Grid

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

Its color palette follows the VGA default palette.

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

  needs gr/font/ufx io/prompt io/fbgrid
  "data/font/atari8.uf1" loaduf1 fbgrid$
  ' gridrtype RTYPE !
  :realias waitkey pos cursor! key ;
