Backends: Vulkan: Separate the pipeline of the dear imgui created windows from the one created with the user's render-pass. (#3455, #3459)
This is mostly for the benefit of multi-viewports.

tabs reordered in the tab list popup. [@Xipiryon]
|
||||
- Metrics: Various tweaks, listing windows front-to-back, greying inactive items when possible.
|
||||
- Demo: Add simple InputText() callbacks demo (aside from the more elaborate ones in 'Examples->Console').
|
||||
- Backends: Vulkan: Some internal refactor aimed at allowing multi-viewport feature to create their
|
||||
own render pass. (#3455, #3459) [@FunMiles]
|
||||
- Examples: Vulkan: Reworked buffer resize handling, fix for Linux/X11. (#3390, #2626) [@RoryO]
|
||||
- Examples: Vulkan: Switch validation layer to use "VK_LAYER_KHRONOS_validation" instead of
|
||||
"VK_LAYER_LUNARG_standard_validation" which is deprecated (#3459) [@FunMiles]

// CHANGELOG
|

// (minor and older changes stripped away, please see git history for details)
|
||||
// 2020-09-07: Vulkan: Added VkPipeline parameter to ImGui_ImplVulkan_RenderDrawData (default to one passed to ImGui_ImplVulkan_Init).
|
||||
// 2020-05-04: Vulkan: Fixed crash if initial frame has no vertices.
|
||||
// 2020-04-26: Vulkan: Fixed edge case where render callbacks wouldn't be called if the ImDrawData didn't have vertices.
|
||||
// 2019-08-01: 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.
