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)

SetKeyboardFocusHere() added assert to prevent passing values smaller than -1 as we may have to outlaw them (I think nobody was using that)

Styles: Added ImGuiStyle::ScaleAllSizes(float) helper to make it easier to have application transition to e.g. High DPI with a matching style.

Added VerticalSeparator() entry point in imgui_internal. Seperator() in an horizontal layout context still does that.

ImFontAtlas: Fixed calling Clear() and rebuilding (broken in 3fe2ecf) thanks @pdoane @mikesart

ImFontAtlas: Added support for CustomRect API to submit custom rectangles to be packed into the atlas / and map them as font glyphs

Minor comments

ImFont: Renamed (supposedly internal) fields (e.g. XAdvance to AdvanceX). Custom text renderers might be affected if they didn't use the GetCharAdvance() helper function.

ImFont: Renamed ImFont::Glyph to ImFontGlyph (for consistency and so ImFontAtlas types can use it without ordering half of the file). Left a redirection type.

ImFontAtlas: Comments and minor reorganization of declaration in header file.

ImFont: Split some building code into a AddGlyph() helper (that custom rect code and imgui_freetype can use)

Comments, debug code (commented), todo list

Fix static misusage error with decent compilers. Error introduced in 4b82759

SetNextWindowPos: added a ImVec2 pivot parameter for positioning a given a center, bottom-right position, etc. As a generalization of SetNextWindowPosCenter() which is now obsolete. This will be useful for combo-like popups as well. ...

Demo: Simple-overlay window uses the SetWindowPos pivot to select a corner to position itself at.

Added io.WantMoveMouse flags from Nav branch so Examples/Binding can already implement it. (#787)

Merge branch 'master' into styles

Internals: moved ButtonRepeat and AllowKeyboardFocus bools/stacks to a generic ItemFlags stack. Merged from Navigation branch.
