VERSION 1.71 (In Progress)
VERSION 1.71 (Released 2019-06-12)
-----------------------------------------------------------------------
Breaking Changes:
- IO: changed AddInputCharacter(unsigned short c) signature to AddInputCharacter(unsigned int c).
- Renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete).
- Window: rendering of child windows outer decorations (e.g. bg color, border, scrollbars) is now
performed as part of their parent window, avoiding the creation of an extraneous draw commands.
If you have overlapping child windows with decorations, and relied on their relative z-order to be
mapped to submission their order, this will affect your rendering. The optimization is disabled
if the parent window has no visual output because it appears to be the most common situation leading
to the creation of overlapping child windows. Please reach out if you are affected by this change!
Other Changes:
- Window: clarified behavior of SetNextWindowContentSize(). Content size is defined as the size available

- Window: Fixed auto-resize with AlwaysVerticalScrollbar or AlwaysHorizontalScrollbar flags.

appear for a single frame after the resize.
- Columns: Fixed Separator from creating an extraneous draw command. (#125)
- Columns: Fixed Selectable with SpanAllColumns flag from creating an extraneous draw command. (#125)
- Separator: Revert 1.70 "Declare its thickness (1.0f) to the layout" change. It's not incorrect
but it breaks existing some layout patterns. Will return back to it when we expose Separator flags.

- Columns: Fixed Separator from creating an extraneous draw command. (#125)
- Columns: Fixed Selectable with SpanAllColumns flag from creating an extraneous draw command. (#125)
- Style: Added style.WindowMenuButtonPosition (left/right, defaults to ImGuiDir_Left) to move the
collapsing/docking button to the other side of the title bar.
- Style: Made window close button cross slightly smaller.
- Log/Capture: Fixed BeginTabItem() label not being included in a text log/capture.
- ImDrawList: Added ImDrawCmd::VtxOffset value to support large meshes (64k+ vertices) using 16-bits indices.
The renderer back-end needs to set 'io.BackendFlags |= ImGuiBackendFlags_RendererHasVtxOffset' to enable
this, and honor the ImDrawCmd::VtxOffset field. Otherwise the value will always be zero.

This is provided for convenience and consistency with VtxOffset.
- ImDrawCallback: Allow to override the signature of ImDrawCallback by #define-ing it. This is meant to
facilitate custom rendering back-ends passing local render-specific data to the draw callback.

fully cleared. Fixed edge-case overflow when adding character 0xFFFF. (#2568). [@NIKE3500]

The library started its life as "ImGui" due to the fact that I didn't give it a proper name when I released 1.0 and had no particular expectation that it would take off. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations (e.g. Unity uses it own implementation of the IMGUI paradigm). To reduce this ambiguity without affecting existing codebases, I have decided on an alternate, longer name "Dear ImGui" that people can use to refer to this specific library. Please try to refer to this library as "Dear ImGui".

Allegro doesn't support them natively, so we have two solutions: convert the indices manually in imgui_impl_allegro5.cpp, or compile dear imgui with 32-bit indices.
You can either modify imconfig.h that comes with Dear ImGui (easier), or set a C++ preprocessor option IMGUI_USER_CONFIG to find to a filename.
We are providing `imconfig_allegro5.h` that enables 32-bit indices.
Note that the back-end supports _BOTH_ 16-bit and 32-bit indices, but 32-bit indices will be slightly faster as they won't require a manual conversion.

Q: How can I tell whether to dispatch mouse/keyboard to Dear ImGui or to my application?
A: You can read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags from the ImGuiIO structure (e.g. if (ImGui::GetIO().WantCaptureMouse) { ... } )
- When 'io.WantCaptureMouse' is set, imgui wants to use your mouse state, and you may want to discard/hide the inputs from the rest of your application.
- When 'io.WantCaptureKeyboard' is set, imgui wants to use your keyboard state, and you may want to discard/hide the inputs from the rest of your application.
