// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2020-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2020-12-04: Misc: Fixed setting of io.DisplaySize to invalid/uninitialized data when after hwnd has been closed.
// 2020-03-03: Inputs: Calling AddInputCharacterUTF16() to support surrogate pairs leading to codepoint >= 0x10000 (for more complete CJK inputs)
// 2020-02-17: Added ImGui_ImplWin32_EnableDpiAwareness(), ImGui_ImplWin32_GetDpiScaleForHwnd(), ImGui_ImplWin32_GetDpiScaleForMonitor() helper functions.
// 2020-01-14: Inputs: Added support for #define IMGUI_IMPL_WIN32_DISABLE_GAMEPAD/IMGUI_IMPL_WIN32_DISABLE_LINKING_XINPUT.

Breaking Changes:
- Added imgui_tables.cpp file! Manually constructed project files will need the new file added!
- Backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/. (#3513)
- Removed redirecting functions/enums names that were marked obsolete in 1.60 (April 2017):
- io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend
@ -126,6 +127,18 @@ Breaking Changes:
Other Changes:
- Tables: added new Tables Beta API as a replacement for old Columns. (#2957, #125)
Check out 'Demo->Tables' for many demos + API comments in imgui.h for details.
- Added 16 functions: BeginTable(), EndTable(),
TableNextRow(), TableNextColumn(), TableSetColumnIndex(), TableGetColumnIndex(), TableGetRowIndex(),
TableSetupColumn(), TableSetupScrollFreeze(),
TableHeadersRow(), TableHeader(), TableSetBgColor(), TableGetSortSpecs(),
TableGetColumnCount(), TableGetColumnName(), TableGetColumnFlags().
- Added 2 structures: ImGuiTableSortSpecs, ImGuiTableColumnSortSpecs.
- Added 2 enums: ImGuiSortDirection, ImGuiTableBgTarget.
- Added 3 flags sets: ImGuiTableFlags (27 flags), ImGuiTableColumnFlags (24 flags), ImGuiTableRowFlags (1 flags).
- Added 5 colors: ImGuiCol_TableHeaderBg, ImGuiCol_TableBorderStrong, ImGuiCol_TableBorderLight, ImGuiCol_TableRowBg, ImGuiCol_TableRowBgAlt.
- Added 1 style var: ImGuiStyleVar_CellPadding.
- Tab Bar: Made it possible to append to an existing tab bar by calling BeginTabBar()/EndTabBar() again.
- Tab Bar: Fixed using more than 128 tabs in a tab bar (scrolling policy recommended).
- Tab Bar: Do not display a tooltip if the name already fits over a given tab. (#3521)

- 2020/XX/XX (1.XX) - Moved IME support functions from io.ImeSetInputScreenPosFn, io.ImeWindowHandle to the PlatformIO api.

- 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API.
- 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures
