442 clipping range of the text.

443 BUF Dynamic array of Emchars specifying what is actually to be

444 drawn.
|
|
445 XPOS X position in pixels where the text should start being drawn.
|
|
446 XOFFSET Number of pixels to be chopped off the left side of the
|
|
447 text. The effect is as if the text were shifted to the
|
|
448 left this many pixels and clipped at XPOS.
|
|
449 CLIP_START Clip everything left of this X position.

450 WIDTH Clip everything right of XPOS + WIDTH.
