Renamed ImGuiNavFlags io.NavFlags to ImGuiConfigFlags io.ConfigFlags. (#787)

Examples: DX11 + Win32: Initial attempt at implementing the viewport/platform api. (WIP/test API) (#1542)

Merge branch 'master' into examples_refactor

Examples: DirectX10, DirectX11: Simplified main example code.

Merge branch 'master' into examples_refactor

Examples: DirectX 9,10,11: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling). (#1495)

Examples: DirectX11: Extracted imgui_impl_dx11.* instead imgui_impl_dx11 and imgui_impl_win32

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.

Examples: Added Changelog to make updates easier.

Added IsAnyMouseDown() helper. ...

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

Nav: Examples: Added commented out io.NavFlags |= ImGuiNavFlags_EnableKeyboard to all examples. (#787)

Nav: Keyboard is now automatically mapped based on io.KeyDown[]. (#787)

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 navigation

Moved extra_fonts/ to misc/fonts/. Moved .natvis file to misc/natvis/ (#1569)

Merge branch 'master' into navigation ...

# Conflicts:
#	imgui.cpp

Examples: Using Dark theme by default. (#707). Tweaked demo code.

Examples: Tweaks formatting.

Merge branch 'master' into navigation

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

Nav: Examples: DirectX11, Glfw+GL3: Basic code to map keyboard inputs when io.NavFlags & ImGuiNavFlags_EnableKeyboard is set. (will iterate/tweak before spreading to other examples). (#787)

Merge branch 'master' into context

Added imgui.natvis helper for visual studio users. Added to examples projects.

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)
