Examples: SDL: Using SDL_WINDOW_INPUT_FOCUS instead of SDL_WINDOW_MOUSE_FOCUS (which is ~~hovered). We should use SDL_CaptureMouse + SDL_WINDOW_MOUSE_CAPTURE_FLAG which requires SDL 2.0.4 will give it a try shortly. (#1559)

Examples: SDL: Fixed mapping of Insert key (#1555, fix bug introduced in #1541)

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

Examples: DirectX9,10,10: Support for CS_DBLCLKS by treating double-click down messages are regular down. (#1538, #754)

Examples: Using IM_OFFSETOF macro. + Comments

CS_DBLCLKS support for DirectX 11

CS_DBLCLKS support for DirectX 10

CS_DBLCLKS support for Directx9

Examples: Visual Studio projects: Disabled extraneous function-level check in Release build.

Examples: Comments about invalid mouse pos.

Examples: DirectX10,DirectX11: Moved call to OMSetRenderTargets() in main loop so example code can integrate more nicely with other code.

Examples: Vulkan: Tweak

Examples: Comments, synched some minor drift between examples + stronger suggestion to use StyleColorsDark().

Renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete).

Examples: DirectX: Using IM_ARRAYSIZE()

Examples: Added null_example/ which is helpful for quick testing on multiple compilers/settings without relyong on graphics library.

Examples: DirectX9: Call EndFrame(), fix for assert added in 9a44d44

Examples: DirectX9: Handle loss of D3D9 device (D3DERR_DEVICELOST). (#1464)

Horizontal mouse wheel support ...

This patch adds support for the horizontal mouse wheel in ImGui. It
affects windows that can be scrolled, as long as the Ctrl key is not
being pressed.

The scrolling speed has been set empirically so that it matches the
scrolling speed on the Firefox browser when the horizontal wheel is
used.

Internally, it adds a MouseHorizWheel to ImGuiIO, which is then used in
NewFrame to scroll the current window.

The SDL/GL2, SDL/GL3, GLFW/GL2 and GLFW/GL3 examples has been modified
to use it.
