ColorPicker / ColorEdit: restore Hue when zeroing Saturation. (#2722, #2770) - changelog, fixed uninitialized variables, tweaks, renaming.

ColorPicker / ColorEdit: restore Hue when zeroing Saturation. (#2722, #2770) ...

Issue is fixed by storing last active color picker color and last hue value when active color picker takes rgb as input. Then if current color picker color matches last active color - hue value will be restored. IDs are not used because ColorEdit4() and ColorWidget4() may call each other in hard-to-predict ways and they both push their own IDs on to the stack. We need hue restoration to happen in entire stack of these widgets if topmost widget used hue restoration. Since these widgets operate on exact same color value - color was chosen as a factor deciding which widgets should restore hue.

TreeNode: Added ImGuiTreeNodeFlags_SpanAvailWidth and ImGuiTreeNodeFlags_SpanFullWidth flags (#2451, #2438, #1897) ...

Added demo bits.

Internal: Offset STB_TEXTURE_K_ defines to remove that change from #2541 + sponsors update.

Remove trailing spaces (grep for ' \r?$' in visual studio)

BeginTabItem: Fixed case where right-most tab would create an extraneous draw calls (probably related to other tab fitting code in 1.73 wip)

Columns: Separator: Fixed a bug where non-visible separators within columns would alter the next row position differently than visible ones. ...

Fixed rounding issues also leading to change of ScrollMax depending on visible items (in particular negative coordinate would be rounded differently)

Fix DragScalar for unsigned types (#2780) ...

decreasing the value was broken on arm64

ColorEdit: Disable Hue edit when Saturation==0 instead of letting Hue values jump around.

DragInt, DragFloat, DragScalar: Using (v_min > v_max) allows locking any edit to the value.

TabBar: feed desired width (sum of unclipped tabs width) into layout system to allow for auto-resize. (#2768) ...

Before 1.71 tab bars fed the sum of current width which created feedback loops in certain situations. Amend f95c77e.

TabBar: improved shrinking for large number of tabs to avoid leaving extraneous space on the right side. Individuals tabs are given integer-rounded width and remainder is spread between tabs left-to-right.

SliderScalar: Improved assert when using U32 or U64 types with a large v_max value. (#2765) ...

+  misc minor stuff.

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

+ minor typo fixes (#2738)

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).

Version 1.73 WIP

Version 1.72b (patch for nav)

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

Internal: Avoid using GImGui multiple times in same function.

Version 1.73 WIP

Version 1.72

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.

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.

InputTextMultiline: Fixed vertical scrolling tracking glitch. ...

Fixed Travis-CI banner address.

Amend 0f86116, renamed to ImGuiKey_KeyPadEnter Changelog.. (#2677, #2005)

Adding an ImGuiKey 'ImGuiKey_EnterSecondary' to support platforms that differentiate the enter (return key) and the numpad enter key.

Columns: Made GetColumnOffset() and GetColumnWidth() behave when there's no column set, consistently with other column functions + fixed Columns demo (#2683)
