* Vulkan: query max anisotropy
...instead of hardcoding it to 4
* Vulkan: use BGFX_CONFIG_MIP_LOD_BIAS
* Vulkan: consider BGFX_CONFIG_PREFER_DISCRETE_GPU at device selection
* Vulkan: implement resizing for textures with backbuffer ratio size
* Vulkan: use correct framebuffer attachment layer and mip
* Vulkan: bind correct image mip
* Cleanup
* Vulkan: add indirect draw support
* Vulkan: add support for BGFX_DEBUG_WIREFRAME
* Vulkan: check all extensions and layers
... not just the first 64
* Vulkan: add support for VPRT
https://github.com/bkaradzic/bgfx/issues/2320
* 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 resize buffer with compute read/write flag error
* only update dynamic buffer with compute read flag

* 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
* display bokeh sample pattern, add bokeh shape, improve look
draw sample pattern to texture and display in ui to see number of samples and their arrangment
add bokeh shape controls
remove adhoc 'sqrt' pattern since display makes existing pattern easier to understand and it looks nicer.
switch to floating point color texture and leave lighting results in linear space until after dof is performed. provides better results and bright spots can make more noticeable bokeh shapes.
change default values to use take more samples at reduced resolution so initial experience when loading the sample is better looking image
* update screenshot, minor change to ui
fix height of ui element so scrollbar not required by default layout
update screenshot
* fix typo in texturev
atleast, i'm pretty sure that's a typo don't see a reason to set width twice
- Fix Android Building
- "entry_android.cpp:157:29: error: no member named 'kErrorRederWriterEof' in namespace 'bx'; did you mean 'kErrorReaderWriterEof'?"
* Implement bokeh depth of field
Implement bokeh depth of field as described in the blog post here:
https://blog.tuxedolabs.com/2018/05/04/bokeh-depth-of-field-in-single-pass.html
Additionally, implement the optimizations discussed in the closing paragraph. Apply the effect in multiple passes. Calculate the circle of confusion and store in the alpha channel while downsampling the image. Then compute depth of field at this lower res, storing sample size in alpha. Then composite the blurred image, based on the sample size. Compositing the lower res like this can lead to blocky edges where there's a depth discontinuity and the blur is just enough. May be an area to improve on.
Provide an alternate means of determining radius of current sample when blurring. I find the blog post's sample pattern to be difficult to directly reason about. It is not obvious, given the parameters, how many samples will be taken. And it can be very many samples. Though the results are good. The 'sqrt' pattern chosen here looks alright and allows for the number of samples to be set directly. If you are going to use this in a project, may be worth exploring additional sample patterns. And certainly update the shader to remove the pattern choice from inside the sample loop.
* fix typo in shader of denoise example
copy/paste error, applying y offset to x component instead
