/* From XC-MISC extension specification:
*
* When an X client connects to an X server, it receives a fixed range
* of resource IDs to use to identify the client's resources inside the
* X server. Xlib hands these out sequentially as needed. When it
* overruns the end of the range, an IDChoice protocol error results.
* Long running clients, or clients that use resource IDs at a rapid
* rate, may encounter this circumstance. When it happens, there are
* usually many resource IDs available, but Xlib doesn't know about
* them.
*
* One approach to solving this problem would be to have Xlib notice
* when a resource is freed and recycle its ID for future use. This
* strategy runs into difficulties because sometimes freeing one
* resource causes others to be freed (for example, when a window is
* destroyed, so are its children). To do a complete job, Xlib would
* have to maintain a large amount of state that currently resides only
* in the server (the entire window tree in the above example). Even if
* a less comprehensive strategy was adopted, such as recycling only
* those IDs that Xlib can identify without maintaining additional
* state, the additional bookkeeping at resource creation and
* destruction time would likely introduce unacceptable overhead.
*
* To avoid the problems listed above, the server's complete knowledge
* of all resource IDs in use by a client is leveraged. This extension
* provides two ways for Xlib to query the server for available
* resource IDs. Xlib can use these extension requests behind the
* scenes when it has exhausted its current pool of resource IDs.
*/
/* If XC-MISC is present, we use it. Otherwise, we fall back to
* allocate X resource ID sequentially to the end without recycling ID
* (just as xlib does).
*
* Sample values:
* resource base: 0x04000000 or 00000100000000000000000000000000b
* resource mask: 0x003FFFFF or 00000000001111111111111111111111b
