373 W Window that the text is to be displayed in.

374 DL Display line that this text is on. The values in the

375 structure are used to determine the vertical position and
|
|
|
376 clipping range of the text.
|
|
|
377 BUF Dynamic array of Emchars specifying what is actually to be
|
|
|
378 drawn.
|
|
|
379 XPOS X position in pixels where the text should start being drawn.
|
|
|
380 XOFFSET Number of pixels to be chopped off the left side of the
|
|
|
381 text. The effect is as if the text were shifted to the
|
|
|
382 left this many pixels and clipped at XPOS.
|
|
|
383 CLIP_START Clip everything left of this X position.
|
|
|
384 WIDTH Clip everything right of XPOS + WIDTH.
|
|
|
385 FINDEX Index for the face cache element describing how to display
|
|
|
386 the text.
