When we first get video, the video component will resize itself. This will
cause the page to be reflowed, but that doesn't trigger an update on the gemini
scrollbar. We therefore need to force an update on the messagepanel. Implement
this by providing an onResize property on the CallView component.
We need to do the same when we change the maxHeight on the video panel.
The same applies to resizing of the MessageComposer. That was previously
handled with a fugly roomView.forceUpdate() from MessageComposer - make it use
the same mechanism.
Finally: the messageComposer is at least 70 pixels, and up to 100 pixels high -
not 36. Fix the auxPanelMaxHeight calculation - and use a static constant
rather than hardcoding the number to avoid this happening again.
Make sure that we *actually* give preference to longer search result
highlights; it turns out that the code that looked like it was doing so has
never worked.
We need to return 'true' from our promise of search result pagination.
Also inline _backPaginateSearch which mostly served to confuse, and use
debuglog instead of checking DEBUG_SCROLL
The dance to avoid doing repeated fill requests on every update is common, so
add it to ScrollPanel. Let onFillRequest return a promise, which prevents any
updates until it completes.
This is required for automatically entering tab-complete mode because
onKeyDown is NOT called in that case, so we need to make sure to have a
membership list hanging around.
RoomView is the parent component which creates MessageComposer AND the status
bar. By making RoomView instantiate TabComplete we can scope instances
correctly rather than relying on singleton behaviour through dispatches. This
also makes communication between status bar and the MessageComposer infinitely
easier since they are now sharing the same TabComplete object.
Refactor the event-tile generation loop to go forwards rather than backwards,
which makes it easier to figure out whether we are displaying a continuation of
the previous event, and whether we need a date separator.
Also only display the date separator at the top of the room if there's no more
scrollback to be shown.
