New era?

I have been exceptionally mostly away in the past two months.
A series of things happened. The project lost its largest source of income a few months ago. Shortly after I ran into some personal issues that have been emotionally draining. Coincidentally this aligned with a long-time planed trip so it was a good timing to disappear for a little bit. I have attended GDC (thanks to BeamNG) in an effort to engage in discussion with some potential sponsors, and generally to engage a little bit of gamedev reality again :)

I am now back home. I have moved offices. Managed to get some financial contributions (G3DVu!, Lucid Games! Aras!) and hopeful that ongoing discussions will eventually allow to fill the gap. Heck, I'm looking into buying a Mac now to get toward settling some of the recurrent scaling/dpi issues.

Dear ImGui is funded by your contributions and needs them to sustain and grow. We can invoice and accommodate to many situations.

Changes

TL;DR

• Add concave polygon rendered for convenience.
• Menus/popup fix erroneous closing regression happening when moving mouse fast.
• Dozens of various fixes.

Breaking Changes:

• More formally obsoleted GetKeyIndex() when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is set.
  It has been unnecessary and a no-op since 1.87 (it returns the same value as passed when used with a 1.87+ backend using io.AddKeyEvent() function). (#4921)
  • Reminder: IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) --> IsKeyPressed(ImGuiKey_XXX)
• ImDrawList: Merged the radius_x/radius_y parameters in AddEllipse(), AddEllipseFilled() and PathEllipticalArcTo() into a single ImVec2 parameter. Exceptionally, because those functions were added recently in 1.90, we are not adding inline redirection functions. The transition is easy and should affect few users. (#2743, #7417) [@cfillion]

Other Changes:

• Windows: Scrollbar visibility decision uses current size when both size and contents size are submitted by API. (#7252)
• Windows: Double-click to collapse may be disabled via key-ownership mechanism. (#7369)
• Windows: BeginChild(): Extend outer resize borders to the edges when there are no corner grips. Essentially affects resizable child windows. (#7440, #1710) [@cfillion]
• Windows: BeginChild(): Resizing logic for child windows evaluates whether per-axis clamping should be applied based on parent scrollbars, not child scrollbars. (#7440, #1710) [@cfillion] Adjust those resizing limits to match window padding rather than inner clipping rectangle.
• Tables: Fixed auto-width columns when using synced-instances of same table, width of one instance would bleed into next one instead of sharing their widths. (#7218)
• Tables: Angled headers: fixed border hit box extending beyond when used within non-scrollable tables. (#7416) [@cfillion]
• Tables: Angled headers: fixed borders not moving back up after TableAngleHeadersRow() stops being called. (#7416) [@cfillion]
• Tables: Angled headers: rounding header size to nearest integers, fixes some issues when using clipper.
• Menus, Popups: Fixed an issue where sibling menu popups re-opening in successive frames would erroneously close the window. While it is technically a popup issue it would generally manifest when fast moving the mouse bottom to top in a sub-menu. (#7325, #7287, #7063)
• ProgressBar: Fixed passing fraction==NaN from leading to a crash. (#7451)
• ListBox: Fixed text-baseline offset when using SameLine()+Text() after a labeled ListBox().
• Drags, Sliders, Inputs: Fixed io.PlatformLocaleDecimalPoint decimal point localization feature not working regression from 1.90.1. (#7389, #6719, #2278) [@GamingMinds-DanielC]
• Style: Added ImGuiStyleVar_TabBorderSize, ImGuiStyleVar_TableAngledHeadersAngle for consistency. (#7411) [@cfillion]
• DrawList: Added AddConcavePolyFilled(), PathFillConcave() concave filling. (#760) [@thedmd] Note that only simple polygons (no self-intersections, no holes) are supported.
• DrawList: Allow AddText() to accept null ranges. (#3615, 7391)
• Docs: added more wiki links to headers of imgui.h/imgui.cpp to facilitate discovery
  of interesting resources, because github doesn't allow Wiki to be crawled by search engines.
  • This is the main wiki: https://github.com/ocornut/imgui/wiki
  • This is the crawlable version: https://github-wiki-see.page/m/ocornut/imgui/wiki ... Adding a link to the crawlable version, even though it is not intended for humans, to increase its search rank.

Changes from 1.90.4 to 1.90.5 related to the Docking branch:

• Backends: Win32: made it so that an appearing viewport showing up doesn't bring its parent to front. (#7354)
