Fixed imgui_impl_opengl3 broken in previous few commits. (#2591, #2593, #2594)

Examples/Backends: Metal: Added support for large meshes (64k+ vertices) with 16-bits indices, enable 'ImGuiBackendFlags_HasVtxOffset' config flag in back-end. (#2591, #2592)

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

Examples/Backends: DirectX9/10/11/12, Vulkan, OpenGL3 (Desktop GL only): Added support for large meshes (64k+ vertices) with 16-bits indices, enable 'ImGuiBackendFlags_HasVtxOffset' config flag in back-end. (#2591)

Changelog, minor tweaks. (#2585)

Examples: imgui_impl_osx: Added mouse cursor support. (#2585, #1873)

Examples: imgui_impl_opengl3: Fix empty printout on shader load. (#2584) ...

Fixed minor bug in CheckShader and CheckProgram

The log_length reported by 
glGetProgramiv(handle, GL_INFO_LOG_LENGTH, &log_length)
will at least return 1, since the string delimiter is also counted.

The old version would always print and empty string to stderr. This is annoying in the emscripten port, since it prints a red error message to the Javascript console. The new version fixes this behavior.

Update changelog, comments, made empty/no-text clipboard return NULL as with other implementation. Minor style tweaks. (#2546) ...

Fixed IMGUI_DISABLE_WIN32_FUNCTIONS not disabling IME code.

Add native mac copy/paste support to match win32 (#2546)

IO: changed AddInputCharacter(unsigned short c) signature to AddInputCharacter(unsigned int c). ...

Examples/Backends: Don't filter characters under 0x10000 before calling io.AddInputCharacter(), the filtering is done in io.AddInputCharacter() itself. This is in prevision for fuller Unicode support. (#2538, #2541)

Version 1.71 WIP + fixed minor typo

Version 1.70

Examples: DirectX9/10/11: Taking reference to device + subsequent merge of this in docking will fix DX9 issue #2524

Examples Readme and Changelog tweaks, added #2527, re-ordered examples/README alphabetically.

Examples: Metal: Add GLFW+Metal example

Examples: Added missing per-renderer local changelogs. (#2037, #1639, #2452)

ImDrawCallback_ResetRenderState: Added Metal.

ImDrawCallback_ResetRenderState, Examples: Added support for reset render state callback. (#2037, #1639, #2452)

Examples: Glut: Added note about missing cursor support. (#2375, #2465)

Examples: SDL: Gamepad support minor amend. Fixes ImGuiBackendFlags_HasGamepad not being set. Enable in Emscripten demo. Tweaks. (#2509, #2484).

Added support to use controllers via SDL_GameController. (#2509) ...

Updated sdl examples to use SDL_INIT_GAMECONTROLLER flag

Examples: SDL: Removed unused code. (#2484)

emscripten: replace shell_minimal.html with 'soft fullscreen' version

Clarified asserts comments + todo entries. (#2500)

Examples: DirectX10/11/12, Allegro, Marmalade: Render functions early out when display size is zero (minimized). (#2496)

Examples: Emscripten: Tweaks for size. (#2494)

Examples: Visual Studio: Updated default platform toolset+sdk in vcproj files from v100+sdk7 (vs2010) to v110+sdk8 (vs2012). This is mostly so we can remove reliance on DXSDK_DIR for the DX10/DX11 example, which if existing and when switching to recent SDK ends up conflicting and creating warnings.

Examples: Emscripten: Fixed error in shell template. (#2494)

Examples: Emscripten: Switched to WebGL1/ES2, Added Changelog, Updated links, Added ignore list, Fixed warning with older versions. Removed reliance on C++11 (would warn on some compiler). Improved html template, removed undesirable options, reduced log size. Tweaked main.cpp. (#2494)

Examples: Removed unused variable (will be used in docking branch tho, undo when merging!)
