405 drawn.

406 XPOS X position in pixels where the text should start being drawn.

407 XOFFSET Number of pixels to be chopped off the left side of the
|
|
|
408 text. The effect is as if the text were shifted to the

409 left this many pixels and clipped at XPOS.

410 CLIP_START Clip everything left of this X position.
