More typos in comments (#2738)

TabBar: fixed single-tab not shrinking their width down. ...

+ minor typo fixes (#2738)

Internals: Renaming window size calc functions.

TabBar: fixed ScrollToBar request creating bouncing loop when tab is larger than available space.

ColorPicker: Made rendering aware of global style alpha of the picker can be faded out. (#2711) ...

Note that some elements won't accurately fade down with the same intensity, and the color wheel when enabled will have small overlap glitches with (style.Alpha < 1.0).

Removing Funding file (unnecessary as we'll switch services)

Explicit narrowing cast from size_t to UINT (#2726) ...

Clang: `non-constant-expression cannot be narrowed from type 'size_t' (aka 'unsigned long long') to 'UINT' (aka 'unsigned int') in initializer list [-Wc++11-narrowing]`

Backends: Vulkan: Added support for specifying multisample count. (#2705, #2706)

Backends: DX11: Fixed GSGetShader() call not passing an initialized instance count, would generally make the debug layer complain (Added in 1.72).

Version 1.73 WIP

Internal: Made ScrollToBringRectIntoView() handle recursing back to scroll parent window, so the function can be called elsewhere (instead of 1 deep recursion done in NavUpdateMoveResult().

Version 1.72b (patch for nav)

Nav: Made hovering non-MenuItem Selectable not re-assign the source item for keyboard navigation.

Scrolling, Nav: Fixed programmatic scroll leading to a slightly incorrect scroll offset when the window has decorations or a menu-bar (broken in 1.71). This was mostly noticeable when a keyboard/gamepad movement led to scrolling the view, or using e.g. SetScrollHereY() function. Fix/amend a0994d74.

Internal refactor: moved all Scroll related functions in a same spot.

Internal: Moved NavScrollToBringItemIntoView() declaration to imgui_internal.h. Fixed spacing missing in 494d804. Fixed changelog wreck from 1.72.

Internal: Avoid using GImGui multiple times in same function.

Internal: Added ImGuiInputTextState::ClearText() helper.

Nav: Fixed an issue with NavFlattened window flag where widgets not entirely fitting in child window (often selectable because of their extruded bits) would be not considered to navigate toward the child window. (#787) ...

This creates a little bit of tension because g.NavDisableHighlight tends to makes the reference point not always visible.

Internal: Added IsMouseDragPastThreshold(). Tweaks. Todo. ...

Demo: Showing how to use the format parameter of Slider/Drag functions to display the name of an enum value instead of the underlying integer value

Fixed Clang 8.0 warning "empty expression statement has no effect; remove unnecessary ';' to silence this" warning [-Wextra-semi-stmt] ...

+ Comment

Internals: Added IMGUI_DEBUG_INI_SETTINGS. Made IMGUI_DEBUG_LOG redefinable in imconfig.h. Comments. Fix to allow Metrics's NodeWindow() being called with a NULL window.

Internals: Merge in minor noise from wip Tables branch to simplify further merging.

ImDrawList: Using ImDrawCornerFlags instead of int in various apis. ...

Demo: Using ImGuiColorEditrFlags instead of int.

imgui_freetype: Initialize FT_MemoryRec_ struct manually (#2686) ...

This fixes gcc warning: missing field 'alloc' initializer [-Wmissing-field-initializers]

Scrolling: Made mouse-wheel scrolling lock the underlying window until the mouse is moved again or until a short delay expires (2 seconds). This allow uninterrupted scroll even if child windows are passing under the mouse cursor. (#2604)

Scrolling: Made it possible for mouse wheel and navigation-triggered scrolling to override a call to SetScrollX()/SetScrollY(), making it possible to use a simpler stateless pattern for auto-scrolling. ...

Demo: Log, Console: Using a simpler stateless pattern for auto-scrolling.
