If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.
- 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext().
- 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection.
- 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen).

- drag float: up/down axis
- drag float: added leeway on edge (e.g. a few invisible steps past the clamp limits)
- tree node / optimization: avoid formatting when clipped.
- tree node: clarify spacing, perhaps provide API to query exact spacing. provide API to draw the primitive. same with Bullet().
- tree node: tree-node/header right-most side doesn't take account of horizontal scrolling.
- tree node: add treenode/treepush int variants? because (void*) cast from int warns on some platforms/settings
- tree node: add treenode/treepush int variants? not there because (void*) cast from int warns on some platforms/settings?
- tree node: try to apply scrolling at time of TreePop() if node was just opened and end of node is past scrolling limits?
- tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer)
- textwrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (git issue #249)
- tree node: tweak color scheme to distinguish headers from selected tree node (#581)
- textwrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249)
- settings: write more decent code to allow saving/loading new fields
- settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file
- style: add window shadows.
