Increased IMGUI_VERSION_NUM to facilitate transition of OSX clipboard support for framework using/embedding any version of imgui. Amend 29d9394. (#2546)

Amend 0f86116, renamed to ImGuiKey_KeyPadEnter Changelog.. (#2677, #2005)

Adding an ImGuiKey 'ImGuiKey_EnterSecondary' to support platforms that differentiate the enter (return key) and the numpad enter key.

Fixed old SetWindowFontScale() api value from not being inherited by child window. Added comments about the right way to scale your UI (load a font at the right side, rebuild atlas, scale style). ...

+ Added missing IMGUI_API marker to the EmptyString storage used by ImGuiTextBuffer. (#2672)

Style: Added style.ColorButtonButton (left/right, defaults to ImGuiDir_Right) to move the color button of ColorEdit3/ColorEdit4 functions to either side of the inputs.

Removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). (#581, #324)

Fixed unnecessary test in UpdateMouseWheel() (thanks PVS). ...

TreeNodeBehavior: avoid computing bg_col for non-framed non-active tree nodes.
Comments, binaries update, minor typos.

Moved ImGuiColumnsFlags erroneously forward declared in imgui.h + demo bit.

Renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Keep redirection typedef (will obsolete).

Prefixed internal structs exposed in imgui.h with a fully qualified name to facilitate auto-generation with cimgui.

fonts/binary_to_compress: display error message when failing to open file + misc comments.

Added 'SetScrollHereX' and 'SetScrollFromPosX' (#1580)

ImDrawListSplitter: Fixed memory leak when using low-level split api (was not affecting ImDrawList api, also this type was added in 1.71 and not advertised as a public-facing feature).

Internals: Renamed GetFrontMostPopupModal() to GetTopMostPopupModal() to be consistent. Renamed other locals to follow that terminology.

Disable -Wpragmas warning in GCC to avoid relying on version checks, as unusual/forks/mods don't appear to always have same warning<>version. (#2618) ...

+ Fix version number in imgui.h

Removed redirecting functions/enums that were obsoleted in version 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME.

Version 1.72 WIP

Version 1.71 + comments

Readme, comments, dear imgui prefixes

ImDrawListSplitter: Don't merge draw commands when crossing a VtxOffset boundary + Renamed fields ImDrawChannels to consistently suggest those are internal structures.

ImDrawListSplitter: Fix idx offset when merging (cef88f6) (#2591)

ImDrawCallback: Allow to override the signature of ImDrawCallback by #define-ing it. This is meant to facilitate custom rendering back-ends passing local render-specific data to the draw callback.

Revert "Changed syntax for (very rarely used) IMGUI_OVERRIDE_DRAWVERT_STRUCT_LAYOUT mechanism, instead you only need to '#define ImDrawVert MyDrawVert' to use this feature, avoiding the need to declare the entire structure within an awkward macro. Using the old macro will now error with a message pointing you to the new method. (#38, #103, #1172, #1231, #2489)" ...

This reverts commit 597c024.

Clarified behavior of SetNextWindowContentSize(). Content size is defined as the size available after removal of WindowPadding on each sides. So SetNextWindowContentSize(ImVec2(100,100)) + auto-resize will always allow submitting a 100x100 item without creating a scrollbar, regarding of WindowPadding.The exact meaning of ContentSize for decorated windows was previously ill-defined.

Comments about obsoleted features version. Todo. Clarify tab bar initial offset (useful if we decide to remove the half-windowpadding clip margin).

ImDrawListSplitter: extracted out of ImDrawList. Down the line we may obsolete the ImDrawList functions and encourage users to store the splitter aside, in the meanwhile ImDrawList holds a splitter. ...

(This will allow columns/table to recurse.)

Renamed ImGuiBackendFlags_HasVtxOffset to ImGuiBackendFlags_RendererHasVtxOffset to match naming convention already used in viewport/docking branch. (#2591) + Fix OpenGL3 code missing flag.

ImDrawList: Added ImDrawCmd::VtxOffset value to support large meshes (64k+ vertices) using 16-bits indices. To enable the feature, the renderer back-end needs to set 'io.BackendFlags |= ImGuiBackendFlags_HasVtxOffset' and honor the ImDrawCmd::VtxOffset field. Otherwise the value will always be zero. This has the advantage of preserving smaller index buffers and allowing to execute on hardware that do not support 32-bits indices. ...

ImDrawList: Added ImDrawCmd::IdxOffset value, equivalent to summing element count for each draw command. This is provided for convenience and consistency with VtxOffset. (#2591)

ImDrawList: Store initial flags for the frame in ImDrawListSharedData, reducing code duplication in setting up the flags.
