12 * Notes on ID translation:
13 *
14 * If a server has multiple clients (in the case of parallel applications)
15 * and N of the clients all create a display list with ID K, does K name
16 * one display list or N different display lists?
17 *
18 * By default, there is one display list named K. If the clients put
19 * identical commands into list K, then this is fine. But if the clients
20 * each put something different into list K when they created it, then this
21 * is a serious problem.
22 *
23 * By zeroing the 'shared_display_lists' configuration option, we can tell
24 * the server to make list K be unique for all N clients. We do this by
25 * translating K into a new, unique ID dependent on which client we're
26 * talking to (curClient->number).
27 *
28 * Same story for texture objects, vertex programs, etc.
29 *
30 * The application can also dynamically switch between shared and private
31 * display lists with:
32 * glChromiumParameteri(GL_SHARED_DISPLAY_LISTS_CR, GL_TRUE)
33 * and
34 * glChromiumParameteri(GL_SHARED_DISPLAY_LISTS_CR, GL_FALSE)
35 *
