Examples: SDL: Note about SDL breaking the IME under Windows (I can't seem a way SDL2 Windows IME implementation can possibly work, the functions are never called/referenced).

Internals: Removed ImGuiDataType_Float2.

Added InputDouble() function. We use a format string instead of a decimal_precision parameter to also for "%e" and variants. (#1011) May transition the other InputXXX function to use format strings as well.

InputFloat: Scientific input. InputText: Added ImGuiInputTextFlags_CharsScientific to add 'e' 'E' to list of characters that can be input. (later useful for #1011)

Nav: Fixed a crash with IMGUI_DEBUG_NAV_SCORING enabled + added info to Metrics.

Examples: GLFW: Don't alter cursor mode if GLFW_CURSOR input mode is GLFW_CURSOR_DISABLED. (#1202) [@PhilCK]

IO: Added ImGuiConfigFlags_NoSetMouseCursors. Added ImGuiBackendFlags_HasMouseCursors, ImGuiBackendFlags_HasSetMousePos. (#787, #1495, #1202)

Added ImGuiBackendFlags for backend to expose its capabilities. Added ImGuiBackendFlags_HasGamepad. (#787, #1542)

IO: Renamed io.WantMoveMouse to io.WantSetMousePos (was added in 1.52, _not_ used by core and only honored by some binding ahead of merging the Nav branch) + internal renaming (#787)

imconfig: Added IMGUI_STB_TRUETYPE_FILENAME, IMGUI_STB_RECT_PACK_FILENAME + documenting IMGUI_DISABLE_STB_XXX flags and hiding IMGUI_STB_NAMESPACE which is misleading. ...

Fixed typos in todo list.

Examples: Renamed applications to emphasis on use of GLFW as a platform framework + minor local tweaks

ImVector: Fixed insert() helper using the = operator (followup to be consistent with 4186c2c)

Fixed enum typo.

Examples: Vulkan: Fix missing subpass dependency ...

Without a dependency between pWaitDstStageMask (COLOR_ATTACHMENT_OUTPUT)
and the render-pass, the UNDEFINED -> COLOR_ATTACHMENT_OPTIMAL transition
might happen before the image is ready to be used.

Examples: Vulkan: Using VK_PRESENT_MODE_MAILBOX_KHR. Disable IMGUI_UNLIMITED_FRAME_RATE by default. Fixed warnings. (#1042)

Demo: Added more complete Combo demo. (#1658)

Nav: InputText: Allow editing text input fields with NavActivate (space). Not sure about that, on one hand it feels more consistent but you can't finish the editing with space to double space (activate + input space) could feel inconsistent. (#787)

Nav: Track nav input source more generally (gamepad vs keyboard) (#787) + update todos and demo tweaks

imgui.h: Various comments and tweaks.

imgui.h: Moved columns lower in the file. Various spacing changes and minor comments.

ImVector: Added copy/assign operators as helpers to ease cloning of data.

ImDrawList: Added Clone() helper function.

ImVector: resize() / push_back() use memcpy() as we are not supposed to be constructor/destructor/operator aware at all. (If we do need to rework ImVector). In turn this will allow us to define assign/copy operators.

ImVector: Using value_type consistently. Spacing.

Update TODO list, minor fix in Readme, comments, Clang -Weverything warning fix in imgui_draw.cpp under Windows.

Moved IM_NEW, IM_DELETE helpers to imgui.h for convenient use by back-ends and user code.

ImVector: Spacing, assert tweaks

Misc: Fix 111ea7a, GetStyleColorName() would assert, removed removed ImGuiCol defines (too much risk/complexity trying to silently ignore it).

Contributing: tweaks, mention screenshots more prominently.

Misc comments, todos + reintroduced removed ImGuiCol defines under !IMGUI_DISABLE_OBSOLETE_FUNCTIONS wrap.
