* \todo
|
|
* This function was intended for stand-alone Mesa. The issue there is that
|
|
* the library doesn't get any notification when a window is closed. In
|
|
* DRI there is a similar but slightly different issue. When GLX 1.3 is
|
|
* supported, there are 3 different functions to destroy a drawable. It
|
|
* should be possible to create GLX protocol (or have it determine which
|
|
* protocol to use based on the type of the drawable) to have one function
|
|
* do the work of 3. For the direct-rendering case, this function could
|
|
* just call the driver's \c __DRIdrawableRec::destroyDrawable function.
|
|
* This would reduce the frequency with which \c __driGarbageCollectDrawables
|
|
* would need to be used. This really should be done as part of the new DRI
|
|
* interface work.
