398 clipping range of the text.

399 BUF Dynamic array of Emchars specifying what is actually to be
|
|
|
400 drawn.

401 XPOS X position in pixels where the text should start being drawn.
|
|
|
402 XOFFSET Number of pixels to be chopped off the left side of the
|
|
|
403 text. The effect is as if the text were shifted to the
|
|
|
404 left this many pixels and clipped at XPOS.
|

405 CLIP_START Clip everything left of this X position.

408 the text.
