// 2021-06:29: *BREAKING CHANGE* Removed 'SDL_Window* window' parameter to ImGui_ImplSDL2_NewFrame() which was unnecessary.
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
// 2021-03-22: Rework global mouse pos availability check listing supported platforms explicitly, effectively fixing mouse access on Raspberry Pi. (#2837, #3950)

Breaking Changes:
- Backends: SDL2: removed unnecessary SDL_Window* parameter from ImGui_ImplSDL2_NewFrame(). (#3244) [@funchal]
Kept inline redirection function (will obsolete).
- Internals: (for custom widgets): because disabled items now sets HoveredId, if you want custom widgets to
not react as hovered when disabled, in the majority of use cases it is preferable to check the "hovered"
return value of ButtonBehavior() rather than (HoveredId == id).
Other Changes:
- Windows: ImGuiWindowFlags_UnsavedDocument/ImGuiTabItmeFlags_UnsavedDocument display a dot instead of a '*' so it
is independent from font style. When in a tab, the dot is displayed at the same position as the close button.

- TabBar: Fixed using more than 32 KB-worth of tab names. (#4176)
- InputInt/InputFloat: When used with Steps values and _ReadOnly flag, the step button look disabled. (#211)
- Drag and Drop: drop target highlight doesn't try to bypass host clipping rectangle. (#4281, #3272)
- Menus: MenuItem() and BeginMenu() are not affected/overlapping when style.SelectableTextAlign is altered.
- Menus: fix hovering a disabled menu or menu item not closing other menus. (#211)
- Nav: Disabled items are not candidate for default focus. (#211, #787)
- Disabled: disabled items set HoveredId, allowing e.g. HoveredIdTimer to function. (#211, #3419) [@rokups]
- Disabled: disabled mode more consistently release active id if the active item got disabled. (#211)
- Disabled: disabled mode doesn't prevent Selectable() from looking selected. (#211)
- Fixed printf-style format checks on non-MinGW flavors. (#4183, #3592)
- Fonts: Functions with a 'float size_pixels' parameter can accept zero if it is set in ImFontSize::SizePixels.
- Fonts: Prefer using U+FFFD character for fallback instead of '?', if available. (#4269)
- Fonts: Use U+FF0E dot character to construct an ellipsis if U+002E '.' is not available. (#4269)
- Fonts: Add U+FFFD ("replacement character") to default asian glyphs ranges. (#4269)
- Fonts: Fix calling ClearTexData() (clearing CPU side font data) triggering an assert in NewFrame(). (#3487)
- Demo: Fixed requirement in 1.83 to link with imgui_demo.cpp if IMGUI_DISABLE_METRICS_WINDOW is not set. (#4171)
Normally the right way to disable compiling the demo is to set IMGUI_DISABLE_DEMO_WINDOWS, but we want to avoid
implying that the file is required.

backends with multiple-contexts BUT is only partially tested and not well supported. It is generally advised to
instead use the multi-viewports feature of docking branch where a single Dear ImGui context can be used accross
multiple windows. (#586, #1851, #2004, #3012, #3934, #4141)

- ImGui_ImplWin32_EnableDpiAwareness() will call SetProcessDpiAwareness() fallback on Windows 8.1 without a manifest.

### Q: I integrated Dear ImGui in my engine and little squares are showing instead of text...
This usually means that: your font texture wasn't uploaded into GPU, or your shader or other rendering state are not reading from the right texture (e.g. texture wasn't bound).
If this happens using the standard backends it is probably that the texture failed to upload, which could happens if for some reason your texture is too big. Also see [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md).
Your renderer is not using the font texture correctly or it hasn't be uploaded to GPU.
- If this happens using the standard backends: A) have you modified the font atlas after `ImGui_ImplXXX_NewFrame()`? B) maybe the texture failed to upload, which could happens if for some reason your texture is too big. Also see [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md).
- If this happens with a custom backend: make sure you have uploaded the font texture to the GPU, that all shaders are rendering states are setup properly (e.g. texture is bound). Compare your code to existing backends and use a graphics debugger such as [RenderDoc](https://renderdoc.org) to debug your rendering states.

- shortcuts: local-style shortcut api, e.g. parse "&Save"
- shortcuts,menus: global-style shortcut api e.g. "Save (CTRL+S)" -> explicit flag for recursing into closed menu
- shortcuts: programmatically access shortcuts "Focus("&Save"))
- menus: hovering a disabled BeginMenu or MenuItem won't close another menu
- menus: menu-bar: main menu-bar could affect clamping of windows position (~ akin to modifying DisplayMin)
- menus: hovering from menu to menu on a menu-bar has 1 frame without any menu, which is a little annoying. ideally either 0 either longer.
- menus: could merge draw call in most cases (how about storing an optional aabb in ImDrawCmd to move the burden of merging in a single spot).

- ImGui::SetScrollHere() -> use ImGui::SetScrollHereY()
- 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing.
- 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future.
- 2021/02/22 (1.82) - win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'.

MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'.
- 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed.
- 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete).
- removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete).
