Drag and Drop: Added ImGuiDragDropFlags_SourceExtern to facilitate interfacing with WM_DROPFILES (#143)

Drag and Drop: Renamed to ImGuiDragDropFlags_SourceNoAutoTooltip to ImGuiDragDropFlags_SourceNoPreviewTooltip (#143)

Using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. (#1380, #1502)

Added ImGuiHoveredFlags_RootAndChildWindows helper for consistency with focused flags. (#1382)

Minor tweaks, comments, spacing fixes

Added ShowFontSelector(), ShowStyleSelector(). (#707)

ImVector: Added ImVector::contains() helper

Merged miscellaneous small stuff (from nav/dock branches).

Added IsAnyWindowFocused() (from Nav branch).

Drag and Drop: Added ImGuiCol_DragDropTarget (#143, #707)

Drag and Drop: Comments

Merge branch 'master' into drag_and_drop ...

# Conflicts:
#	imgui.cpp
#	imgui.h
#	imgui_internal.h

Renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing()

Added GetFrameHeight() function (used to be SmallSquareSize internally)

IsWindowFocused() refactor will flags. (#1382) ...

Marked IsRootWindowFocused() as obsolete in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow).
Marked IsRootWindowOrAnyChildFocused() as obsolete in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows).

Reordered ImGuiHoveredFlags to match upcoming ImGuiFocusedFlags (#1382)

IsWindowHovered(): split ImGuiHoveredFlags_FlattenChild into separate ChildWindows and RootWindow flags. Allowing more combination and a better symetry with IsWindowFocused() flags. (#1382)

Alignment + removed comments

Renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. (#600, #1330)

Comments (#822)

Merge branch 'master' into drag_and_drop ...

# Conflicts:
#	imgui.cpp
#	imgui.h

Obsoleted old functions: SetScrollPosHere (marked obsolete in 1.42, July 2015). GetWindowFont(), GetWindowFontSize() (marked obsolete in 1.48, March 2016)

Added an implementation of SetItemDefaultFocus() in the master branch for combo patterns to use and be more forward-compatible. (#787)

ImFont: Added GetDebugName() helper.

Exposed BeginCombo() publicly.

Sorted typedefs/enumations forward declarations in imgui.h

SetNextWindowContentSize() adjust for client->window size, but the fate of borders isn't really clear for now (until now we always tried to make borders not affect layout, so if we want a 200x200 fully visible space with borders and zero window padding user need to include the borders) (#1490)

Comments

Removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete). (#246, #519, #1444)
