ImVector: Fixed a oddly unqualified return type in the assignment operator (I assume C++ handles it nicely as this never warned anywhere, but it is completely unintentional).

Examples: Vulkan: Fixed some minor discrepency in the SDL+Vulkan example to match the Glfw+Vulkan example. (cc #2097)

ImDrawList: Fixed AddConvexPolyFilled() undefined behavior when passing points_count smaller than 3, in particular, points_count==0 could lead to a memory stomp if the draw list was previously empty.

Examples: Referring to missing gamepad support in back-end that are missing it.

ArrowButton(): Fixed arrow shape being horizontally misaligned by (FramePadding.y-FramePadding.x) if they are different. ...

Demo: Added extra usage of AlignTextToFramePadding() in a more visible section.

Contributing, Issue Template

Added Fonts readme details and links to Sweet16 font. (#2085)

Fix file names (#2083)

BeginMenu(): Fixed menu popup horizontal offset being off the item in the menu bar when WindowPadding=0.0f.

ColorPicker: Replaced the Separator with a Spacing call. (#2068)

Examples: Using "dear imgui" terminology in all examples headers/comments + fix minor typo.

Fix MSVC's C4312 warning about casting user texture type to void* in ImageButton (#2080)

Internals: Replace unsigned short with ImWchar when dealing with character storage (missing cases) + in imgui_impl_ file keep using neutral type everywhere, added missing explicit cast in three bindings. (#2078)

Internals: Replace unsigned short with ImWchar when dealing with character storage. (#2078)

DragFloat: Disabled using power curve when one edge is FLT_MAX (broken in 1.61). Disabled setting a default drag speed when one edge is FLT_MAX. (#2024)

DragFloat: Fixed a situation where dragging with value rounding enabled or with a power curve erroneously wrapped the value to one of the min/max edge. (#2024, #708, #320, #2075).

Nav, Focus: Fixed ImGuiWindowFlags_NoBringToFrontOnFocus windows not being restoring focus properly after the main menu bar or last focused window is deactivated.

example_glfw_vulkan was missing a reference to imgui_widgets.cpp (#2071, #2036)

Fixed calling SetNextWindowSize()/SetWindowSize() with non-integer values leading to accidental alteration of window position. We now round the provided size. (#2067)

Fixed calling DestroyContext() always saving .ini data with the current context instead of the supplied context pointer. (#2066)

Version 1.66 WIP

Version 1.65

Renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. (#1718, #2036) ...

If you were conveniently using the imgui copy of those STB headers in your project, you will have to update your include paths.
The reason for this change is to avoid conflicts for projects that may also be importing their own copy of the STB libraries. Note that imgui's copy of stb_textedit.h is modified.

Refactor: Tweaked and improved the sectioning to facilitate grepping/moving around and applied to all files. (#2036)

Refactor: Moved ImFile functions. (#2036)

Refactor: Moved one indentation level in the bulk of the ShowMetricsWindow() function. Should appear as a small diff if whitespaces changes are ignored. (#2036)

Refactor: moved low-layout helpers to imgui_widgets.cpp (Spacing, Dummy, NewLine, Separator, etc.) (#2036)

Internals: Refactor: Moved render functions to their own section. (#2036)

Nav: Removed the [Beta] tag from various descriptions of the gamepad/keyboard navigation system. Although it is not perfect and will keep being improved, it is fairly functional and used by many. (#787)

Renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + changed ImGuiIO layout.
