arguments:
state - 'test' to display lcd test pattern, 'norm' to return to normal display.
function:
Generates a multi-color test pattern that can be used to troubleshoot display issues. The pattern
consists of seven equally spaced color bands with thirty-two variations of each color (darkest on
the left and brightest on the right). The color transitions should appear smooth and uniform.
Abnormal displays and/or display connections can be detected by abrupt color changes that may
appear as non-deliberate lines in the middle of the pattern. The seven colors from top to bottom
are: green, blue, cyan, white, magenta, yellow, and red (each separated by a thin black line). Each of
the four corners are outlined with a one-pixel wide white square with cross-hairs; an off-center
image can thus be detected by an incomplete white box in at least one of the four corners. The
touchpanel input is disabled while in test mode (returned to normal with 'lcd norm').
