/*  PA_NO_EFFECT 	Used as a place filler, executes no operation.
    PA_PRINT 	Text just appears (printed)
    PA_SCROLL_UP 	Text scrolls up through the display.
    PA_SCROLL_DOWN 	Text scrolls down through the display.
    PA_SCROLL_LEFT 	Text scrolls right to left on the display.
    PA_SCROLL_RIGHT 	Text scrolls left to right on the display.
    PA_SPRITE 	Text enters and exits using user defined sprite.
    PA_SLICE 	Text enters and exits a slice (column) at a time from the right.
    PA_MESH 	Text enters and exits in columns moving in alternate direction (U/D)
    PA_FADE 	Text enters and exits by fading from/to 0 and intensity setting.
    PA_DISSOLVE 	Text dissolves from one display to another.
    PA_BLINDS 	Text is replaced behind vertical blinds.
    PA_RANDOM 	Text enters and exits as random dots.
    PA_WIPE 	Text appears/disappears one column at a time, looks like it is wiped on and off.
    PA_WIPE_CURSOR 	WIPE with a light bar ahead of the change.
    PA_SCAN_HORIZ 	Scan the LED column one at a time then appears/disappear at end.
    PA_SCAN_HORIZX 	Scan a blank column through the text one column at a time then appears/disappear at end.
    PA_SCAN_VERT 	Scan the LED row one at a time then appears/disappear at end.
    PA_SCAN_VERTX 	Scan a blank row through the text one row at a time then appears/disappear at end.
    PA_OPENING 	Appear and disappear from the center of the display, towards the ends.
    PA_OPENING_CURSOR 	OPENING with light bars ahead of the change.
    PA_CLOSING 	Appear and disappear from the ends of the display, towards the middle.
    PA_CLOSING_CURSOR 	CLOSING with light bars ahead of the change.
    PA_SCROLL_UP_LEFT 	Text moves in/out in a diagonal path up and left (North East)
    PA_SCROLL_UP_RIGHT 	Text moves in/out in a diagonal path up and right (North West)
    PA_SCROLL_DOWN_LEFT 	Text moves in/out in a diagonal path down and left (South East)
    PA_SCROLL_DOWN_RIGHT 	Text moves in/out in a diagonal path down and right (North West)
    PA_GROW_UP 	Text grows from the bottom up and shrinks from the top down.
    PA_GROW_DOWN 	Text grows from the top down and and shrinks from the bottom up. */
