// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2021-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2021-10-15: Vulkan: Call vkCmdSetScissor() at the end of render a full-viewport to reduce likehood of issues with people using VK_DYNAMIC_STATE_SCISSOR in their app without calling vkCmdSetScissor() explicitly every frame.
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
// 2021-03-22: Vulkan: Fix mapped memory validation error when buffer sizes are not multiple of VkPhysicalDeviceLimits::nonCoherentAtomSize.
// 2021-02-18: Vulkan: Change blending equation to preserve alpha in output buffer.

// Note: at this point both vkCmdSetViewport() and vkCmdSetScissor() have been called.
// Our last values will leak into user/application rendering IF:
// - Your app uses a pipeline with VK_DYNAMIC_STATE_VIEWPORT or VK_DYNAMIC_STATE_SCISSOR dynamic state
// - And you forgot to call vkCmdSetViewport() and vkCmdSetScissor() yourself to explicitely set that state.
// If you use VK_DYNAMIC_STATE_VIEWPORT or VK_DYNAMIC_STATE_SCISSOR you are responsible for setting the values before rendering.
// In theory we should aim to backup/restore those values but I am not sure this is possible.
// We perform a call to vkCmdSetScissor() to set back a full viewport which is likely to fix things for 99% users but technically this is not perfect. (See github #4644)
