              Diagonal line patterns

This pattern can be used to adjust the vertical
and horizontal scaling in video processors
in different resolutions. The test uses higher
resolution assets for 480p when in that mode.

The angle increment for line rotation can be
adjusted by fractions up to 1/20th of a degree
with #GX#G and #GY#G The angle can be adjusted with
#GL#G and #GR#G

The bars can be set to auto-rotate with #GA#G.
