Obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display..(#1599) ...

Examples: Updated examples.

Added IsAnyMouseDown() helper. ...

Examples: DirectX9/10/11: Using IsAnyMouseDown() instead of local function.

Merge branch 'context' ...

Added ImGuiKey_Space, mapped in every examples. Will be required for navigation. (#787)

Examples: Organized header files to make available features more visible.

Merge branch 'master' into context

Examples: Using #include "imgui.h" instead of <imgui.h> appear correct-er as per standard? xcode+clang are very nitpicky there.

Examples: Made the Win32 proc handlers not assert if there is no active context yet, to be more flexible with creation order. (#1565)

Examples: Updated for reorganized context functions. Calling CreateContext(), DestroyContext() in example code. Removed Shutdown() from binding code. (#1565, #586, #992, #1007, #1558)

Examples: Allegro, Apple, DirectX9/10/11, Glfw+Vulkan :Added support for horizontal mouse wheel. (#1463)

Added ImGuiKey_Insert for future use. Setup in all example bindings. (#1541)

Examples: DirectX9/10/11: Comments about CS_DBLCLKS + formatting tweaks. (#1538)

CS_DBLCLKS support for Directx9

Examples: DirectX: Using IM_ARRAYSIZE()

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)

Examples: DirectX9/10/11: Tweak usage of SetCapture/ReleaseCapture. (#1375) ...

ps: DirectX 12 example (#302) may want to adopt that as well.

Examples: DirectX9/10/11: Added WM_SYSKEYDOWN / WM_SYSKEYUP handlers so e.g. VK_MENU can be read.

Examples: DirectX9/10/11: Renamed WndProc handler to use a generic Win32 name + returning 0 to all messages is more correct.

Examples: DirectX9: Using SetCapture/ReleaseCapture to get correct behavior (#1375)

Fixed compilation for #1375 + coding style fixes.

Capture/release window in DX9 implementation ...

This helps a lot when the user drags a slider but carries the cursor offscreen before releasing the button - without the capturing, the slider will "stick" to the mouse cursor even after the button has been released. (This should generally be added to all Windows implementations - I won't mind doing it if you think it's a good idea.)

Nav/Examples: honoring the io.WantMoveMouse flag in most common examples (#323) ...

Missing support Vulkan (#549), Apple (#575, #247), SDL (#58, #356),
Allegro, Marmalade (#368, #375)

Examples: DirectX9/10/11: Comments

Examples: DirectX9: Clarified texture release code (#1163)

Examples: DirectX9: Explicitely setting viewport to match that other examples are doing (#937)

Examples: DirectX9-10-11: Only call Windows' SetCursor(NULL) when io.MouseDrawCursor is set (#585, #909)

Examples: Accessing ImVector fields directly, feel less stl-ey and fix renderer side assert when render list only contains a callback (#810)

Examples: DirectX9: Removing spaces (#663)

Example: DirectX9: Backup and restore all state

Examples: DirectX9: Removed dependency on dx3x9.h so it can be used in a DirectXMath.h only environment (#611)
