currently: ImGui::SetNextWindowRefreshPolicy(ImGuiWindowRefreshFlags_TryToAvoidRefresh);
- This is NOT meant to replace frame-wide/app-wide idle mode.
- This is another tool: the idea that a given window could avoid refresh and reuse last frame contents.
- I think it needs to be backed by a careful and smart design overall (refresh policy, load balancing, making it easy and obvious to user).
- It's not there yet, this is currently a toy for experimenting.
My other issues with this:
- It appears to be very simple, but skipping most of Begin() logic will inevitably lead to tricky/confusing bugs. Let's see how it goes.
- I don't like very much that this opens a door to varying inconsistencies
- I don't like very much that it can lead us to situation where the lazy refresh gets disabled in bulk due to some reason (e.g. resizing a dock space) and we get sucked in the temptation to update for idle rather than update for dynamism.
- Simplify and compact some code. Shallow tweaks.
- Add comments.
- Add concave shape demo.
- Remove coarse culling.
- Remove nested types to match coding style and for consistent type nams when translated to other languages.
- Merged ClassifyNode() and ReclassifyNode().
- Extracted ImTriangleIsClockwise().
- Hold copy of points inside nodes instead of pointing to them.

WIP add PathFillConcave(), AddConcavePolyFilled()
* remove use of 'auto'
* IsConvex -> ImPathIsConvex
* Triangulator -> ImTriangulator
* ImTriangulator: split declaration from definition, ImTriangulator can be put in the header if necessary
* ImTriangulator: Add node list flip to reverse winding order and handle degenerate cases
* ImTriangulator: Remove _HeapStorage, always require scratch buffer to be provided
* ImTriangulator: Use ImTriangleContainsPoint
* AddConcavePolyFilled: Clone AddConvexPolyFilled and use triangulator
* AddConcavePolyFilled: Remove ImDrawListEx_AddPolyFilled_xxx
* AddConcavePolyFilled: Use _Data->TempBuffer in triangulator
* AddConcavePolyFilled:
Note that using io.FontGlobalScale or SetWindowFontScale(), with are legacy-ish, partially supported features, can still lead to unrounded sizes and same issues.
