InputText, Examples/SDL: Emulate \t input if back-end doesn't provide it. (#1336, #2467) ...

+ Fix some output filename in SDL build batch files.

InputText: Fixed ImGuiInputTextFlags_AllowTabInput leading to two tabs characters being inserted if the back-end provided both Key and Character input. (#2467, #1336)

InputText: Work-around for buggy standard libraries where isprint('\t') returns true. (#2467, #1336) ...

Not using isprint. + todo items.

InputText: Fixed selection background starts rendering one frame after the cursor movement when first transitioning from no-selection to has-selection. (Bug in 1.69) (#2436) [@Nazg-Gul]

InputText: Simplify read-only code path.

Comments, todo list, remove trailing spaces.

Version 1.70 WIP

Version 1.69, comments, typos

Internals: Fixed Navigation from reaching ImGuiItemFlags_Disabled items (#211) + Examples comments

TabBar: Reworked scrolling policy (when ImGuiTabBarFlags_FittingPolicyScroll is set) to teleport the view when aiming at a tab far away the visible section, and otherwise accelerate the scrolling speed to cap the scrolling time to 0.3 seconds.

TabBar: Fixed Tab tooltip code making drag and drop tooltip disappear during the frame where the drag payload activate a tab.

Fixed Clang and PVS warnings.

InputText: Fixed c779fbb leading to display of the wrong buffer when resizing a buffer. (#2400, #2006, #1443, #1008).

Internal: Removed unused fields from ImGuiMenuColumns.

Added ImGuiColorEditFlagsFlags_InputHSV. (#2383, #2384)

ColorEdit: Fixed tooltip not honoring the ImGuiColorEditFlags_NoAlpha contract of never reading the 4th float in the array (value was read and discarded). (#2384)

TabBar: Fixed ImGuiTabItemFlags_SetSelected being ignored if the tab is not visible (with scrolling policy enabled) or if is currently appearing.

Made ImS8 and ImS16 explicitly signed in case some crazy SDK decide to flip the signedness over. (#2408)

Internals: ColorEdit: Minor optimizations. Initialize internal arrays as static const, avoid unnecessary HSV->RGB conversion.

Demo: Renamed ShowHelpMarker() -> HelpMarker(). Fixed minor PVS warning. Removed unnecessary casts.

InputTextWithHint: Fix for Password fields. Update changelog, demo. (#2400)

Added InputTextWithHint() (#2400) ...

    Added InputTextHinted

InputText: Moving some code in anticipation of supporting hint display with password. This commit is aimed at having no visible side effect. (#2400)

Fixed IsItemDeactivated()/IsItemDeactivatedAfterEdit() from not correctly returning true when tabbing out of a focusable widget (Input/Slider/Drag) in most situations. (#2215, #1875) ...

+ Minor renaming of a local variable in widget code.

Internal: Tabbing/Focus: Tidying up old code, moved some state to context instead of window. Storing new data will allow us to fix the bug mentioned in #2215 (probably in next commit).

MenuItem, Selectable: Fixed disabled widget interfering with navigation (fix c2db7f63 in 1.67).

Internal: Tabbing: Tweaks to FocusableItemRegister and using the standard mechanism to allow/block Tab being interpreting by tabbing instead of InputText() widget.

Internal: Text: Extracted TextUnformatted into TextEx over which we can freely atter the signature. Clarified current large text behavior of TextUnformatted with explicit ImGuiTextFlags_NoWidthForLargeClippedText flag (always set).

Text: Fixed large Text/TextUnformatted call not declaring its size when starting below the lower point of the current clipping rectangle. Somehow this bug has been there since v1.0! It was hardly noticeable but would affect the scrolling range, which in turn would affect some scrolling request functions when called during the opening frame of a window.

Renamed GetOverlayDrawList() to GetForegroundDrawList() for consistency. Kept redirection function (will obsolete). (#2391) ...

Demo: Using GetBackgroundDrawList() and GetForegroundDrawList() in "Custom Rendering" demo.
