Examples: OpenGL: Added support for glew and glad OpenGL loaders out of the box. (#2001, #2002). Changelog, tweaks, applied changes to SDL+OpenGL3 example.

WIP on configurable OpenGL loader. (#2001, #2002)

Examples: Vulkan: Fixed handling of VkSurfaceCapabilitiesKHR::maxImageCount = 0 case. Tweaked present mode selections.

Examples: imgui_impl_vulkan: Comments (re)

Examples: imgui_impl_vulkan: Comments

Examples: Cast to ImTextureID instead of void* when assigning to TexId. Applied to all examples. (#2015)

imgui_impl_dx12: Cast to ImTextureID instead of void* to enable redefinition of ImTextureID (#2015, #301)

imgui_impl_opengl3: Advertised as a ES2/ES3 renderer. Defaults to ES3 on Android. Default on "#version 300 es" on ES 3. (#2002, #1873)

imgui_impl_win32: Don't redefine WIN32_LEAN_AND_MEAN if already defined (#2014)

Examples: Fix 'How to build' instructions for SDL2 examples (#2012)

imgui_impl_opengl3.cpp Using GLES3 on IOS instead of gl3w. (#2002, #1873) ...

Not modifying the main.cpp yet because we need to test GL ES 3 context creation on iOS (only imgui_impl_opengl3.cpp was tested).

Examples: OpenGL2: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications. (#1996)

Changelog for #1989

imgui_impl_dx11: Using ID3D11Factory instead of ID3D11Factory1 (#1989)

imgui_impl_glfw, imgui_impl_sdl: Workaround for Emscripten which doesn't seem to handle focus related calls. (#1941)

Added Visual Studio 2017+ build cruft to Ignore List (.vs/ folder)

imgui_impl_opengl3: Comments. (#1987)

Examples: imgui_impl_opengl3.cpp Using #ifdef GL_SAMPLER_BINDING instead of if (glBindSampler) (#1985)

Examples: imgui_impl_osx: Fix for incorrect DeltaTime calculation on mac OS. (#1978)

Examples: OpenGL3: Tweaks, added changelog. (#1941)

Examples; imgui_impl_opengl3.cpp to work with Emscripten (#1941) ...

* Add some ifdefs to add emscripten specific params and includes

* Update imgui_impl_opengl3.cpp

* Update imgui_impl_opengl3.cpp

* Update imgui_impl_opengl3.cpp

* replace __EMSCRIPTEN_BUILD__ with __EMSCRIPTEN__

* replace GLFW_INCLUDE_ES3 with direct header

* removing useless glfw include

* Making call to glPolygonMode() optional

Examples: Using fully qualified "Dear ImGui" name in window titles.

Examples: SDL: Removed SDL_HAS_WARP_MOUSE_GLOBAL in the non-viewport branch. (#1954) (+1 squashed commits)

Examples: Tweaked the main.cpp example structure for all examples. (There are a few hidden agendas here: 1) I would like to avoid encouraging people from using the implicit "Debug" window, and promote using Begin/End. In spite of my best attempt, there are a few feature of the upcoming docking system that cannot work 100% properly for the implicit Debug window, so future proof let's not put that feature in the spotlight too much for new users. 2) Moved dumb hardcoded positions into a single spot that can be replaced with a viewport relative position and not affect other demo windows. 3) Calling ShowDemoWindow before anything else, also for the benefit of a specific docking demo which will have an ordering constraint which is not really problematic in a real app but shouldn't be put forward in the demo.

Examples: DX10, DX11: Fixed unreleased resources in Init and Shutdown functions. (#1944)

Examples: include for intptr_t on tdm-gcc + mingw32 (#1936) + mouse buttons comments

Examples: OpenGL3: Added shaders more versions of GLSL + made the example app default to GL 3.0 + GLSL 130 (instead of GL 3.2 + GLSL 150) unless on Mac. (#1938, #1900, #1513, #1466, etc.)

OpenGL3: Added error output when shaders fail to compile / link. (#1938)

Examples: Comments, Demo: Log early out, TODO. (#1553)

Examples: Comments + shallow coding convention tweak to be consistent across examples and with imgui_impl_osx
