Style: Added PopupRounding setting. (#1112)

Style: Added a default StyleColorsLight(). (#707)

Style: Removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. (#707)

Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding.

Minor comments, tweaks

io.OptNoCursorBlink -> io.OptCursorBlink (#1427)

Added io.OptNoCursorBlink option to disable cursor blinking. (#1427). Renamed io.OSXBehaviors to io.OptMacOSXBehaviors. Should affect users as the compile-time default is usually enough. (#473, #650)

IsWindowHovered(): Added ImGuiHoveredFlags_FlattenChilds flag. Made IsRootWindowOrAnyChildHovered() obsolete in favor of IsWindowHovered( ImGuiHoveredFlags_FlattenChilds) (#1382, #1404)

Update imgui.h

Examples: Added a bunch of comments/referencs related to io.WantCaptureMouse, io.WantCaptureKeyboard (#1262, #1237, #1219, #635, #1058, #1051, #912, #533, #703, #446, #459, #364, #213, #52, and more)

Demo: Comments (#1408)

Added assertions and comments for incorrect use/understanding of IsWindowFocused() etc. functions

Examples: Added more comments near the fonts loading section, to catch common questions and errors (e.g. #1397, #1366, #1341, #1222, #1193, #1115, #951, etc.)

Styles: Moved Classic colors code to imgui_draw.cpp. Sneakily added a StyleColorsDark() function.

Version 1.53 WIP

IO: Tracking extra mouse dragging data which is convenient for implementating various manual drag and drop patterns.

Version 1.52

Comments

NewFrame: Allow MovedWindow setting the ImGuiWindowFlags_NoInputs after moving has started in order to be able to detect windows below it, which is useful for e.g. docking mechanisms.

Exposed IM_ARRAYSIZE() in imgui.h

Font: Renamed ImFont::Clear() to ImFont::ClearOutputData() for consistency with what ImFontAtlas does. DisplayOffset is set by constructor but not reset by ClearOutputData. (#1349)

Added OpenPopupOnItemClick(); helper which mimic BeginPopupContextItem() but doesn't do the open. ...

Made the color popups uses this standard function so they handle reopening a context menu.

IsItemHovered(), IsWindowHovered(): added flags to enable various and more specific behavior. Will enable improvements for popups/context menus and drag'n drop. (relate ~#439, #1013, #143, #925) ...

The legacy confusing IsItemRectHovered(), IsWindowRectHovered() can be completely removed now.
Changed IsWindowHovered() behavior with default parameter: it now return false is the window is blocked by a popup.
Demo: Added tests for those two functions.

Moved IMGUI_DISABLE_OBSOLETE_FUNCTIONS block lower in the imgui.h file so obsolete functions can use flags. Also sane to quarantine them outside of the respectable area.

IO: reordering some supposedly private fields.

Begin: Marked 5 parameters version of Begin() as obsolete. Now waiting for a riot to happen!

BeginPopupContextItem() now supports a NULL string identifier and uses the last item ID if available. For interactive items (that have an ID) this works! For non interactive items we assert.

Rnamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete).

TreeNode: Added ImGuiTreeNodeFlags_FramePadding flag

Comments (clarifying whether types are to be considered as flags or regular, non combinable enums)
