* HIShape
|
|
*
|
|
* Discussion:
|
|
* HIShape is an abstract shape object for use with some of the
|
|
* HIToolbox APIs. It is designed as a replacement for RgnHandles
|
|
* (though it is currently implemented in terms of them at the time
|
|
* of this writing). This abstraction will allow us to avoid using
|
|
* QD types in our APIs, particularly in HIView.
|
|
*
|
|
* One of the biggest benefits of HIShape is that we have mutable
|
|
* and immutable variants. This means that immutable shapes can be
|
|
* created and passed around and 'copied' very quickly, since they
|
|
* are actually refcounted when copied. This avoids needing to do
|
|
* the handle-to-handle copies that occur right now with
|
|
* RgnHandle-based APIs.
