I am using MPW to develop an application. In that application, I am
using controls (custom built) that use PICT's. For some reason, which
I can not understand, the following code perfectly "dims" the controls
on any machine except a MacPlus. Anyone possibly know why?
LoadResource((Handle)picture);
DrawPicture(picture, &pict_list->bounds);
if (pict_list->active == 0) { /* I.e. it is dim. */
PenMode(srcBic);
PenPat(qd.gray);
PaintRect(&pict_list->bounds);
PenNormal();
}
In fact, instead of the "dim" affect caused by the gray pattern putting
holes in the picture, is appears that a black pattern is actually
used, since the picture simply disappears (white-ed out).

'src' modes should only be used for CopyBits and that sort of thing-- for pen and line drawing use the 'pat' modes. PenMode(patBic); (This restriction was removed in the Mac SE)
