Examples: GLFW, SDL: Preserve DisplayFramebufferScale when main viewport is minimized. (This is particularly useful for the viewport branch because we are not supporting per-viewport frame-buffer scale. It fixes windows not refreshing when main viewport is minimized.) (#2416)

Demo: InputText: Demonstrating use of ImGuiInputTextFlags_CallbackResize. (#2006, #1443, #1008).

Added GetGlyphRangesVietnamese() helper. (#2403)

Fix typos. (#2413)

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.

Examples: DirectX9: Minor changes to match the other DirectX examples more closely. (#2394)

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

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

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.

Nav: Fixed Ctrl+Tab keeping active InputText() of a previous window active after the switch. (#2380)

Comments and Issue Template

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

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

Added GetBackgroundDrawList() helper to quickly get access to a ImDrawList that will be rendered behind every other windows. (#2391)

Examples: OpenGL: Fix to be able to run on ES 2.0 / WebGL 1.0. [@rmitton, @gabrielcuvillier]

ColorPicker: Fix assertion when running in a collapsed window and dragging its title bar (#2389)

Misc: Asserting in NewFrame() if style.WindowMinSize is zero or smaller than (1.0f,1.0f). Internal: ImHash functions tweaks. Added InputText() to query status section.

InputInt, InputScalar: +/- buttons now respects the natural type limits instead of overflowing or underflowing the value.

DragScalar, InputScalar, SliderScalar: Added support for u8/s8/u16/s16 data types. We are reusing function instances for larger types to reduce code size. (#643, #320, #708, #1011)

Renamed ColorEdit/ColorPicker's ImGuiColorEditFlags_RGB/_HSV/_HEX flags to respectively ImGuiColorEditFlags_DisplayRGB/_DisplayHSV/_DisplayHex. This is anticipation of adding new flags to ColorEdit/ColorPicker functions which would make those ambiguous. (#2384) [@haldean]

Added px_render_imgui.h (#1935)

Update README.md

Merge branch 'allegro-touch' of https://github.com/dos1/imgui into dos1-allegro-touch ...

# Conflicts:
#	examples/imgui_impl_allegro5.cpp

Plot: Fixed divide-by-zero in PlotLines() when passing a count of 1. (#2387) [@Lectem]

InputText: Fixed various display corruption related to swapping the underlying buffer while a input widget is active (both for writable and read-only paths). Often they would manifest when manipulating the scrollbar of a multi-line input text.

Log/Capture: Fixed extraneous leading carriage return. Fixed an issue when empty string on a new line would not emit a carriage return.

Log/Capture: Fixed LogXXX functions 'auto_open_depth' parameter being treated as an absolute tree depth instead of a relative one. Fixed CollapsingHeader trailing ascii representation being "#" instead of "##". Minor tidying up the of code.
