Fonts: Fix calling ClearTexData() (clearing CPU side font data) triggering an assert in NewFrame(). ( #3487 ) + Backends: added additional assert to facilitate detecting user understand they haven't initialized a backend.

Backends: support for multiple imgui context with little testing ( #586 , #1851 , #2004 , #3012 , #3934 , #4141 )
...
I believe more renderer backends should work. GLFW/Win32/SDL/Vulkan probably have many issues.

Backends: moved global to a data structure to facilitate support for multi-contexts. ( #586 , #1851 , #2004 , #3012 , #3934 , #4141 )
...
This is NOT enable multi-contexts for any backends

Backends: Vulkan: Fix mapped memory validation error when buffer sizes are not multiple of VkPhysicalDeviceLimits::nonCoherentAtomSize. ( #3957 )
...
If using Vulkan backend and either vertex_size or index_size is not aligned to VkPhysicalDeviceLimits::nonCoherentAtomSize, then the call to vkFlushMappedMemoryRanges in ImGui_ImplVulkan_RenderDrawData will result to validation error.

Backends: Rework blending equation to preserve alpha in output buffer accross all backends. ( #2693 , #2764 , #2766 , #2873 , #3447 , #3813 , #3816 )
...
Some of the viewport ideas from #2766 are not in there yet (e.g. Vulkan: setting compositeAlpha based on cap.supportedCompositeAlpha)

Backends: Using SetTexID() consistently instead of assigning to ->TexID. May make the later obsolete eventually.

Backends: Vulkan: Rework support for custom function/symbol loader ( #3759 , #3227 ), add ImGui_ImplVulkan_LoadFunctions (amend 6001c54)
...
Making it a separate function allows to use/test this with our examples or any code using the VulkanH helper called before ImGui_ImplVulkan_Init()

Backends: Vulkan: Support for custom function/symbol loader ( #3759 , #3227 )
...
- It adds an optional feature to support dynamic linkage of Vulkan instead of using default linkage.
- It is now possible to have several potentially working implementation and whenever the Vulkan library was available it can work.

Backends: Vulkan: Add override for the subpass to reference during VkPipeline creation. ( #3579 )
...
This allows for binding the pipeline/sending draw commands
(via `ImGui_ImplVulkan_RenderDrawData`) against any subpass, rather than
being restricted to only the first subpass.
Without this, attempting to bind the pipeline against a subpass other than
the first one results in validation layer errors and, at worst, some drivers
failing if the subpass attachments differ.
