Other Changes:
- Backends: DX11: Fixed GSGetShader() call not passing an initialized instance count,
would generally make the debug layer complain (Added in 1.72).
- Backends: Vulkan: Added support for specifying multisample count.
Set ImGui_ImplVulkan_InitInfo::MSAASamples to one of the VkSampleCountFlagBits values
to use, default is non-multisampled as before. (#2705, #2706) [@vilya]

// 2019-05-29: Vulkan: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
// 2019-04-30: Vulkan: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
// 2019-04-04: *BREAKING CHANGE*: Vulkan: Added ImageCount/MinImageCount fields in ImGui_ImplVulkan_InitInfo, required for initialization (was previously a hard #define IMGUI_VK_QUEUED_FRAMES 2). Added ImGui_ImplVulkan_SetMinImageCount().
