// This class provides two very important functions. First provides a
|
|
// mechanism for which multiple panes can share the same pattern without
|
|
// duplicating the pattern data for each instance.
|
|
//
|
|
// Second, this class provides a method of drawing that pattern relative
|
|
// to any point.
|
|
//
|
|
// The internals of this class distinguish between patterns that are
|
|
// 8-bits or less in depth from those that are 16 or 32 bits deep. This
|
|
// is necessary because QuickDraw draws the patterns differently depending
|
|
// on that criteria.
|
|
//
|
|
// In order to draw an "shallow" (those <= 8 bits deep) you simply need to
|
|
// offset the target port origin the appropriate ammount and then fill.
|
|
//
|
|
// "Deep" patterns (those > 8 bits deep) can not be predictably drawn
|
|
// relative to a specific point in the destination port. No matter what
|
|
// you do to the port origin, the pattern will continue to be drawn from
|
|
// some global relative point. As I recall there's some low memory global
|
|
// that denotes the offset. Even if you get the low memory global and try
|
|
// to compute a global-relative transformation, your pattern will not
|
|
// necessarily blit in the right orientation. Video card hardware can
|
|
// accelerate the pattern drawing, and may not use the same relative
|
|
// point. Sounds like fun, huh?
|
|
//
|
|
// I just thought I'd document this so when you look at the code you don't
|
|
// think: "gee, why didn't he just use FillCRect() for all the patterns?"
