Other Changes:
- Window: Fixed using non-zero pivot in SetNextWindowPos() when the window is collapsed. (#3433)
- Nav: Fixed navigation resuming on first visible item when using gamepad. [@rokups]
- Nav: Fixed using Alt to toggle the Menu layer when inside a Modal window. (#787)
- InputText: Added selection helpers in ImGuiInputTextCallbackData().
- InputText: Added ImGuiInputTextFlags_CallbackEdit to modify internally owned buffer after an edit.
(note that InputText() already returns true on edit, the callback is useful mainly to manipulate the
underlying buffer while focus is active).
- InputText: Fixed using ImGuiInputTextFlags_Password with InputTextMultiline(). (#3427, #3428)
It is a rather unusual or useless combination of features but no reason it shouldn't work!
- DragFloat, DragScalar: Fixed ImGuiSliderFlags_ClampOnInput not being honored in the special case
where v_min == v_max. (#3361)
- BeginMenuBar: Fixed minor bug where CursorPosMax gets pushed to CursorPos prior to calling BeginMenuBar(),

and amends the change done in 1.76 which only affected cases were _OpenOnArrow flag was set.
(This is also necessary to support full multi/range-select/drag and drop operations.)
- Tab Bar: Keep tab item close button visible while dragging a tab (independent of hovering state).
- Tab Bar: Fixed a small bug where toggling a tab bar from Reorderable to not Reorderable would leave
tabs reordered in the tab list popup. [@Xipiryon]
- Metrics: Various tweaks, listing windows front-to-back, greying inactive items when possible.
- Demo: Add simple InputText() callbacks demo (aside from the more elaborate ones in 'Examples->Console').
- Examples: Vulkan: Reworked buffer resize handling, fix for Linux/X11. (#3390, #2626) [@RoryO]

- You can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert
and get a _similar_ effect as previous uses of power >1.0f.
See https://github.com/ocornut/imgui/issues/3361 for all details.
For shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`.
Kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar().
For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used.

- nav: Home/End behavior when navigable item is not fully visible at the edge of scrolling? should be backtrack to keep item into view?
- nav: NavScrollToBringItemIntoView() with item bigger than view should focus top-right? Repro: using Nav in "About Window"
- nav: wrap around logic to allow e.g. grid based layout (pressing NavRight on the right-most element would go to the next row, etc.). see internal's NavMoveRequestTryWrapping().
- nav: patterns to make it possible for arrows key to update selection

- nav: restore/find nearest NavId when current one disappear (e.g. pressed a button that disappear, or perhaps auto restoring when current button change name)
- nav: SetItemDefaultFocus() level of priority, so widget like Selectable when inside a popup could claim a low-priority default focus on the first selected iem
- nav: NavFlattened: ESC on a flattened child should select something.
- nav: NavFlattened: broken: in typical usage scenario, the items of a fully clipped child are currently not considered to enter into a NavFlattened child.
- nav: NavFlattened: init request doesn't select items that are part of a NavFlattened child
- nav: NavFlattened: cannot access menu-bar of a flattened child window with Alt/menu key (not a very common use case..).
- nav/treenode: Left within a tree node block as a fallback (ImGuiTreeNodeFlags_NavLeftJumpsBackHere by default?)
- nav: simulate right-click or context activation? (SHIFT+F10)
- nav/tabbing: refactor old tabbing system and turn into navigation, should pass through all widgets (in submission order?).
