Add a Time Line view (see class CTimeLine)

Mock-up

Also an idea, show operations over time using a gantt chart

problem: adding CHorSplitterWindows and CTimeLineView creates problem, the ownerdrawn controls are nolonger updated correctly, and closing the logview windows runs into an assertion.

It looks like some window-messages like WM_MEASUREITEM and WM_CLOSE are not delivered to the Logview anymore.

After talking to nenad we solved this problem, however, I forgot to record the solution :( part of it was 'not a problem' because WM_CLOSE is only ever delivered to top-level windows (so was never delivered to Logview in the first place)

Debugview's class MainFrame is a CTabbedFrameImpl<CMainFrame, CDotNetTabCtrl<SelectedTabItem>>

The next step to isolate this problem is to make the class CMainFrame from the POC also inherit from that.

Maybe it is a problem related to this: http://forums.codeguru.com/showthread.php?337200-CComboBox-MeasureItem(-)-is-not-called

although:

• it does not explain the assertion on close
• we do not explicitly assign ID's anywhere

I integrated the CTimeLine control into Debugview++, it can be enabled at compile time using using SelectedTabItem = CLogViewTabItem2; however when it is enabled some window messages cause endless recursion and a stack overflow. For example adding an 'exclude' process filter but using the context menu should call OnViewProcessExclude, but this now crashes with a stack overflow.

for now the timeline feature is disabled until this is resolved.
