Backends: Vulkan: (Breaking) full font upload is performed by ImGui_ImplVulkan_CreateFontsTexture(), no need for user code to create or provide a command-buffer. Removed ImGui_ImplVulkan_DestroyFontUploadObjects(). (#6943, #6715, #6327, #3743, #4618)
See changes in example_glfw_vulkan/main.cpp and example_sdl2_vulkan/main.cpp for reference.

// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2023-11-10: *BREAKING CHANGE*: Removed parameter from ImGui_ImplVulkan_CreateFontsTexture(): backend now creates its own command-buffer to upload fonts.
|
||||
// *BREAKING CHANGE*: Removed ImGui_ImplVulkan_DestroyFontUploadObjects() which is now unecessary as we create and destroy those objects in the backend.
|
||||
// ImGui_ImplVulkan_CreateFontsTexture() is automatically called by NewFrame() the first time.
|
||||
// You can call ImGui_ImplVulkan_CreateFontsTexture() again to recreate the font atlas texture.
|
||||
// Added ImGui_ImplVulkan_DestroyFontsTexture() but you probably never need to call this.
|
||||
// 2023-07-04: Vulkan: Added optional support for VK_KHR_dynamic_rendering. User needs to set init_info->UseDynamicRendering = true and init_info->ColorAttachmentFormat.
|
||||
// 2023-01-02: Vulkan: Fixed sampler passed to ImGui_ImplVulkan_AddTexture() not being honored + removed a bunch of duplicate code.
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
