| 2435 | * \todo |
| 2436 | * This function was intended for stand-alone Mesa. The issue there is that |
| 2437 | * the library doesn't get any notification when a window is closed. In |
| 2438 | * DRI there is a similar but slightly different issue. When GLX 1.3 is |
| 2439 | * supported, there are 3 different functions to destroy a drawable. It |
| 2440 | * should be possible to create GLX protocol (or have it determine which |
| 2441 | * protocol to use based on the type of the drawable) to have one function |
| 2442 | * do the work of 3. For the direct-rendering case, this function could |
| 2443 | * just call the driver's \c __DRIdrawableRec::destroyDrawable function. |
| 2444 | * This would reduce the frequency with which \c __driGarbageCollectDrawables |
| 2445 | * would need to be used. This really should be done as part of the new DRI |
| 2446 | * interface work. |
