* Vulkan: allow setting image debug name
* Vulkan: record multiple frames ahead of the GPU
...instead of stalling on the CPU after each submit. Controllable with init.resolution.maxFrameLatency, same as the D3D11/12 backends.
* Vulkan: some additional checks at swapchain creation
* Vulkan: stall for screenshot
* Vulkan: move blit out of render pass
* Vulkan: deferred framebuffer deletion
* Vulkan: fix cubemap blit
* Cleanup
* Vulkan: storage image must have GENERAL layout and has no sampler
* Vulkan: use slightly more fine-grained barriers
* Vulkan: readTexture should stall, too
* Cleanup
* Vulkan: selective acquire
Don't acquire a swapchain image if no view renders to the backbuffer, avoiding stalls due to vsync or reaching the backbuffer limit
* Vulkan: deferred program and state cache deletion
* Vulkan: fix debug blit
* Fix out of bounds index for unknown device types
* Vulkan: Insert barrier before image host reads
* Vulkan: Make commands wait for the wait semaphore
Making commands wait at BOTTOM_OF_PIPE is a no-op, resulting in instant execution
* Vulkan: Insert barrier between views/dispatches instead of waiting on the host
* Vulkan: Fix determination of access flag from image layout
This fixes two write-after-write races with copy commands after a layout transition to VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL
* Add BGFX_MAX_FRAME_LATENCY define
Affected backends either used a magic value of 3 or defined their own XX_MAX_FRAMES_IN_FLIGHT to be 3
* Vulkan: Include indirect draw in pipeline barrier
* Vulkan: honor init.resolution.numBackBuffers for swapchain size
* Make max frame latency configurable at compile time
When using this compute shader, the following validation errors appear.
This patch fixes the issue.

* [vulkan] Vulkan API auto-selection for latest available.
- Selects for the maximum vulkan API version available on the host's vulkan driver for a created instance.
- Stores the created instance's vulkan API version on RendererContextVK.
- Created instance's vulkan API version dumped using BX_TRACE in MAJOR.MINOR.PATCH format.
- Physical Device's vulkan API version dumped in MAJOR.MINOR.PATCH format.
* Address code review notes.
- Actually use `vkEnumerateInstanceVersion` if it exists.
- Remove "bgfx supported" vulkan api static array.
* D3D12: Fix readback for non-zero mip
* Fix blit with non-zero mip
This required clamping the blit extents to the mip size, which is moved out of the renderers now
* Assert formatting
* Adds UAV support for D3D12, Vulkan and reworked support for OpenGL, D3D11
UAV support is now uniform across compute and draw.
To set a UAV you just use bgfx::setImage() and IMAGE2D in the shader, just like in compute.
Due to these changes shaders will have to be recompiled.
The changes include:
- D3D11 requires patching of the UAV slot number (which is now done by modifying the DXBC instead of using a macro)
- If the DXBC binary includes a debug chunk, that is also patched to match the new slot number
- All the other renderers don't need any kind of patching
- There are some shader annotations to better convert the UAV format used in hlsl to spirv
Possibility of further enhancements:
- bgfx::setViewFrameBuffer() only supports binding to a framebuffer or, using BGFX_INVALID_HANDLE, to bind the default backbuffer. This doesn't allow for the case where there is no need to bind to either one of them, for example when using a fragment shader only to read and write to an UAV.
* Bump shader version, because they need to be recompiled.
When resizing the window, there's a race condition between the
validation of vkCreateSwapchainKHR's arguments and the actual
size of the window.
This ignores the validation warning when vkCreateSwapchainKHR succeeds.
On some graphic drivers vkAcquireNextImage and vkQueuePresentKHR
may return VK_SUBOPTIMAL_KHR. This is being handled as an error, which
leads to those frames being unnecessarily skipped.
* Improves handling of window resizes on vulkan (avoids crashes)
* Change to previous commit as requested.
Rebased and added refresh swapchain check inside updateResolution(),
similar to renderer_d3d12.cpp.
On some platforms (Windows) the framebuffer size becomes 0x0 when
the window is minimized. This leads to a validation error and
subsequently crashes.
This change correctly cleans up semaphores and the swapchain.
