* 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
