- Added imgui_tables.cpp file! Manually constructed project files will need the new file added!
- Backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/. (#3513)
- Removed redirecting functions/enums names that were marked obsolete in 1.60 (April 2017):
- Renamed ImDrawList::AddBezierCurve() to ImDrawList::AddBezierCubic(). Kept inline redirection function (will obsolete).
- Renamed ImDrawList::PathBezierCurveTo() to ImDrawList::PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete).
- Removed redirecting functions/enums names that were marked obsolete in 1.60 (April 2018):
- io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend
- ImGui::IsAnyWindowFocused() -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow)
- ImGui::IsAnyWindowHovered() -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow)

- Removed redirecting functions/enums names that were marked obsolete in 1.61 (May 2018):
- InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X was value for decimal_precision.
- same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter.
- Removed redirecting functions/enums names that were marked obsolete in 1.63 (August 2018):
- ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit().
- ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg
- ImGuiInputTextCallback -> use ImGuiTextEditCallback
- ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData
- If you were still using the old names, while you are cleaning up, considering enabling
IMGUI_DISABLE_OBSOLETE_FUNCTIONS in imconfig.h even temporarily to have a pass at finding
and removing up old API calls, if any remaining.

- Drag and Drop: Fix drag and drop to tie same-size drop targets by choosen the later one. Fixes dragging
into a full-window-sized dockspace inside a zero-padded window. (#3519, #2717) [@Black-Cat]
- Checkbox: Added CheckboxFlags() helper with int* type.
- Clipper: Fixed incorrect end-list positioning when using ImGuiListClipper with 1 item (bug in 1.79). (#3663) [@nyorain]
- InputText: Fixed updating cursor/selection position when a callback altered the buffer in a way
where the byte count is unchanged but the decoded character count changes. (#3587) [@gqw]

- Metrics: Rebranded as "Dear ImGui Metrics/Debugger" to clarify its purpose.
- ImDrawList: Added ImDrawList::AddQuadBezierCurve(), ImDrawList::PathQuadBezierCurveTo() quadratic bezier
helpers. (#3127, #3664, #3665) [@aiekick]
- Fonts: Updated GetGlyphRangesJapanese() to include a larger 2999 ideograms selection of Joyo/Jinmeiyo
kanjis, from the previous 1946 ideograms selection. This will consume a some more memory but be generally
much more fitting for Japanese display, until we switch to a more dynamic atlas. (#3627) [@vaiorabbit]

HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI
----------------------------------------------
- Overwrite all the sources files except for imconfig.h (if you have made modification to your copy of imconfig.h)
- Or maintain your own branch where you have imconfig.h modified.
- Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over master.
- You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file.
- Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes.
If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed
from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will
likely be a comment about it. Please report any issue to the GitHub page!
- Try to keep your copy of dear imgui reasonably up to date.
- To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file.
- Try to keep your copy of Dear ImGui reasonably up to date.
GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE
---------------------------------------------------------------
- Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library.
- In the majority of cases you should be able to use unmodified backends files available in the examples/ folder.
- In the majority of cases you should be able to use unmodified backends files available in the backends/ folder.
- Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system.
It is recommended you build and statically link the .cpp files as part of your project and NOT as shared library (DLL).
- You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types.

0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks.
- We uses a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone.
Your code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
