Internals: Wired a ImGuiItemStatusFlags_ValueChanged into ItemStatusFlags, for an hypothetical IsItemValueChanged() function. (#2034)

Rearrange header comments to find enums easily + fixed inconsistent sorting.

InputText: Improved sturdiness if the ResizeCallback purposefully modify data->BufTextLen or data->BufSize. (#2006, #1443, #1008)

InputText: Fix ResizeCallback callback on restoring initial value with Escape key. Avoid over-allocating for InitialText storage. (#2006, #1443, #1008)

Added optional misc/stl/imgui_stl.h wrapper to use with STL types (e.g. InputText with std::string). (#2035, #2006, #1443, #1008)

InputText: callback InsertChars() support resize callbacks correctly (followup to 24ff259) + fixed demo to use those functions. (#2006, #1443, #1008).

InputText: Fixed a few pathological crash cases on single-line InputText widget with multiple millions characters worth of contents. Because the current text drawing function reserve for a worst-case amount of vertices and how we handle horizontal clipping, we currently just avoid displaying those single-line widgets when they are over a threshold of 2 millions characters, until a better solution is found.

InputText: Fixed not tracking the cursor horizontally When modifying the text buffer through a callback.

ImDrawList: Large text passed to AddText() are being scanned for their end in order to avoid pre-reserving too many vertices.

ImDrawList: Fixed clipping of leading lines above the clipping rectangle from counting in the worst case vertices reservation. (fix code added in #200!)

Internals: InputText: Renaming. Comments.

InputText: Renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete).

InputText: Added support for buffer size/capacity changes via the ImGuiInputTextFlags_CallbackResize flag. (#2006, #1443, #1008).

InputText: Internal renaming of some fields + final copy uses edit_state.CurLenA+1 instead of buf_size.

InputText: Fixed minor off-by-one issue when submitting a buffer size smaller than the initial zero-terminated buffer contents.

InputText: (Breaking change) removed ImGuiTextEditCallbackData::ReadOnly since it is a duplication of (ImGuiTextEditCallbackData::Flags & ImGuiInputTextFlags_ReadOnly) (#211)

Added IMGUI_VERSION_NUM for easy compile-time testing. (#2025)

Added links to Discourse forums.

Internals: Moved code out of SliderBehaviorT to reduce code bloat and also because caller may have use for the grab_bb for styling purposes.

Update README.md

Internals: Added ImTextCountUtf8BytesFromChar() helper.

SplitterBehavior: Fix for when the sizes are already under the minimum desired size.

Fixed assertion when transitioning from an active ID to another within a group, affecting ColorPicker (broken in 1.62). Made ActiveIdIsAlive track the actual ID to avoid incorrect polling in BeginGroup/EndGroup when the ID changes within the group. (#2023, #820, #956, #1875).

Metrics: Added io.MetricsActiveAllocations, moving away from the cross-context global counters than we previously used. (#1565, #1599, #586)

Selectable: Added ImGuiSelectableFlags_Disabled flag in the public API. (#211)

Nav: NavWindowingList doesn't save to .ini file. TODO entries.

TODO + added missing _None enum for some internals flags.

Internals: Extracted RenderMouseCursor() out of EndFrame(). Moved to imgui_draw.cpp along with RenderArrowPointingAt(). Comments. (#2013)
