(There are two additional unhandled flags that only affect padding: '-' and ' '. Formatting flags don't make sense in a SliderInt's format string, so I've omitted them)
Altered ItemAdd() clipping rule to keep previous-frame ActiveId unclipped to support that late commit.
Also, MarkItemEdited() may in theory need to do:
if (g.ActiveIdPreviousFrame == id)
g.ActiveIdPreviousFrameHasBeenEditedBefore = true;
But this should already be set so not adding now.
- Afaik the "to allow ImGuiListClipper to function" was added early during Tables development (prior to commit 55) and later replaced by support in ImGuiListCipper, it seems unnecessary.
- Also removed RowPosY2 being accted in TableEndCell().

This commit is a preparation toward adding ImGui apis with explicit context
and making ImGui applications being able to use multiple context at the same time
whatever their concurrency model.
This commit modifies ImGuiInputTextCallback, ImGuiListClipper and ImGuiStackSize so those classes do not to depend on GImGui context anymore.
About ImGuiInputTextCallback:
- ImGuiInputTextCallback depends on ImGuiContext because it has a
`InsertChars` method adding character to `g.InputTextState`
- To make ImGuiInputTextCallback aware of which context to use, the
appropriate context is given as argument of ImGuiInputTextCallback
constructor.
About ImGuiListClipper:
- ImGuiListClipper apply to a context through its `Begin`, `End`, and `Step`
method.
- To make ImGuiListClipper aware of which context to use, the
appropriate context is given as argument of ImGuiListClipper
constructor.
- Since the behavior is different than previously the class has been
renamed ImGuiListClipperEx
- In order to preserve backward compatibility, a subclass of ImGuiListClipperEx
named ImGuiListClipper has been defined and forward the implicit context
to ImGuiListClipperEx parent.
About ImGuiTextFilter:
- ImGuiTextFilter depends on the implicit context because the Draw(..)
method call ImGui::InputText(...)
- Instead from that commit the Draw(...) method takes an explicit context
as first argument
- Since the behavior is different than previously the class has been
renamed ImGuiTextFilterEx
- In order to preserve backward compatibility, a subclass of ImGuiTextFilterEx
named ImGuiTextFilter has been defined. This subclass has a draw method
override which and forward the implicit context to the parent class Draw(...)
About ImGuiStackSizes:
- ImGuiStackSizes was depending on ImGuiContext because of its
`SetToCurrentState` and `CompareWithCurrentState` method
- ImGuiStackSizes is an helper object use
for comparing state of context. It does not necessarily need to
compare the same context. For that reason, as opposed to previous
classes it takes the context it wants to compare to as argument of
its method.
- For this occasion `SetToCurrentState` and `CompareWithCurrentState`
have been renamed `SetToContextState` and `CompareWithContextState`
to match the new method signature.

This commit is a preparation toward adding ImGui apis with explicit context
and making ImGui applications being able to use multiple context at the same time
whatever their concurrency model.
About ImGuiIO:
- ImGuiIO depends on ImGuiContext because some of its method want to event to `g.InputEventQueue`.
- To make ImGuiIO aware of the context to use, context which creates the ImGuiIO is given as argument of ImGuiIO constructor.
- The assert `IM_ASSERT(&g.IO == this && "Can only add events to current context.")` has been removed since it does not make sense anymore
NOTE: ImGuiIO could be completely independent of ImGuiContext if the InputEventQueue was moved from ImGuiContext to ImGuiIO, but since
ImGuiIO is a public class it would expose InputEvent type. Solving this problem is out of the current scope, but it is interesting to notice.
