the shape and look of arrows. Made default arrow stroked. (#5233, #2431, #2235, #6730, #8243)
Legacy arrow: size: (0.60f,0.70f), thickness: 0.0f
New arrow: size: (0.72f,0.40f), thickness: 0.30f
- TreeNode:
- TreeNodeGetOpen(): added flags parameter to allow passing `ImGuiTreeNodeFlags_DefaultOpen`
or `ImGuiTreeNodeFlags_Leaf`. (#9569, #9592, #3823, #9251) [@adalisk-emikhaylov, @Yaki-Blake]
- ImVec2: added a check for cases where a custom `IM_VEC2_CLASS_EXTRA` macro
adds an extra `operator=` to ImVec2. This isn't supported but should not
be needed as you should have a constructor to convert from your type to ImVec2.
