draw TEXT string
Custom image primitive
Text <color> <x> <y> <fontname> <"text ">
<color> = available colors
<x> = position of left edge of page in pixels
<y> = position of top edge of page in pixels
<fontname> = available fonts
<text> = approx. 30 characters (must be enclosed by quotes)
None
Draws a user-defined text string. It uses five (5) parameters.
The first is color. The next two are the X and Y coordinates for
the upper left corner of the starting position of the string. The
fourth parameter selects the font. (Recall that only #0 Sys 16
and #1 OPIX 9 are full alphanumeric sets.) The last parameter
is the text string. If the string is longer than one word, it must
be contained inside quotation marks.
The FMTU command instructs the generator to use the new
setting. The ALLU command updates hardware to the new setting
and redraws the test image.

None
Temporarily changes how the signal levels are determined for
a given color intensity level. The default method uses black as
the 0% reference level and peak video as the 100% level. Inserting
TOBL moves the 0% reference point to the blanking (blacker
than black) pedestal level. The reference point remains shifted
only for as long as the image is displayed.
