ability to manually control the batch delay at runtime

[Antoine Martin]

So that applications can tell us when things don't need refreshing so much.

r11606 adds the required functions to both "xpra control" and the server dbus interface (#904).

Example usage: say you want to temporarily cap screen updates at 10fps, you would:

• call LockBatchDelay(wid, 100) to force batching at 100ms minimum (note: we don't allow the batch delay to be set lower than what the heuristics have set previously, as they're very rarely wrong, and tend to underestimate anyway)
• then just call UnlockBatchDelay(wid) when the storm has passed

The control interface also supports the "*" syntax to mean all windows. With dbus, you have to specify individual windows by id.

@calvinko: is that enough for your needs?

@antoine: Yes. thank you.

OK, closing. Feel free to re-open if you need more.
