Combo: When peeking into the popup window for alignment we check if the window was active, which is more correct. (no known issue in current codebase, but we'll need that change for later)

DragDrop: Added IsDragDropActive() helper which is useful for binding to decide how to handle mouse inputs.

TreeNode: node with the ImGuiTreeNodeFlags_Leaf flag correctly disable highlight when DragDrop is active. (#143, #581)

Version 1.54 WIP

ListBox() changed signature of ListBox() to match Combo(). Still not very happy about not using const char** anymore. (#931)

Version 1.53

Moving window doesn't use accumulating MouseDelta so straying out of boundaries keeps moved window at the same spot.

Misc comments, removed duplicated IM_ARRAYSIZE macro in imgui_demo.cpp (it is now declared in imgui.h)

Renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete).

Comments

Internals: Added IM_NEW, IM_DELETE helper macros (#1517, #484, #504)

Various zealous warning fixes (Clang).

Removed reliance on ImU64 type for the ImDrawList assert. (#1184)

Various zealous warning fixes (thanks Clang).

Columns: Made PixelsToOffsetNorm() properly symetrical to OffsetNormToPixels() (#125)

Columns: Fixed dragging when using a same of columns multiple times in the frame. (#125)

Drag and Drop: Disable tracking mouse button ownership when an external drag source is active, to make it easier to achieve drag and drop over multiple OS windows. (#143)

ImDrawList, Font: Fixed bug introduced in 531c11d (#1519)

Internals: String functions uses size_t in their signature

ImDrawList: Added ImDrawListFlags for AA settings. ImDrawList doesn't directly depends on GImGui anymore.

Begin: Moved modal darkening draw block

ImDrawList: Removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Anti-aliasing is controlled via the regular style.AntiAliased flags.

ImDrawList: Small refactor toward removing dependency on GImGui + PushClipRectFullscreen now correctly uses data provided by imgui which can takes account of DisplaySize + Removed static variable in PathArcToFast() which caused linking issues to some.

ImDrawList: Comments

Active Modal window always set the WantCaptureKeyboard flag (#744)

BeginPopup: Moved flags into individual BeginPopupXXX calls/implementations and outside of BeginPopupex(). Removed _NoResize flag which is extraneous with AlwaysAutoResize.

InputText: renamed ImGuiInputTextFlags_DisableUndo to ImGuiInputTextFlags_NoUndoRedo (#1506, #1508)

Added a flag for text input to disable undo / redo

Columns: Fixed previous commit (wrong chunk commited) (#125)

Columns: Internal: Columns have their no set of flags so NoResize can be setup by internal code. (#125)
