Xpra: Ticket #874: don't send pixels for iconified windows

This was not a problem before, because we used to unmap the windows. But now that we use the proper iconified state, the window is still mapped and we still get damage events. There is nothing wrong with sending window updates, that's how the window managers can show a window preview in the taskbar for example, but we shouldn't be doing it at full speed. I have a patch which re-uses the go_idle / no_idle methods - but it isn't 100% safe: if the source was idle, we can end up resuming a window-source that is still iconified.

attachment set to throttle-iconified-windows.patch

this works - just needs guarding against no_idle called when still iconified

status changed from new to assigned

r9542 does this - will backport.

I have also spotted some issues with wm-state updates: "iconic" is an attribute of WindowModel but we handle state changes in the superclass.. which can cause errors.

status changed from assigned to closed

resolution set to fixed

"iconic" fixes:

in trunk, the whole window message handler function has now been moved since OR and tray windows should not be processing those messages anyway: r9545 (fairly big change)

in 0.15: we only filter out the change to IconicState for OR windows (safer)
