* This object is wrapped in a GrBackendDrawableInfo and passed in as an argument to
* drawBackendGpu() calls on an SkDrawable. The drawable will use this info to inject direct
* Vulkan calls into our stream of GPU draws.
* The SkDrawable is given a secondary VkCommandBuffer in which to record draws. The GPU backend
* will then execute that command buffer within a render pass it is using for its own draws. The
* drawable is also given the attachment of the color index, a compatible VkRenderPass, and the
* VkFormat of the color attachment so that it can make VkPipeline objects for the draws. The
* SkDrawable must not alter the state of the VkRenderpass or sub pass.
* Additionally, the SkDrawable may fill in the passed in fDrawBounds with the bounds of the draws
* that it submits to the command buffer. This will be used by the GPU backend for setting the
* bounds in vkCmdBeginRenderPass. If fDrawBounds is not updated, we will assume that the entire
* attachment may have been written to.
* The SkDrawable is always allowed to create its own command buffers and submit them to the queue
* to render offscreen textures which will be sampled in draws added to the passed in
* VkCommandBuffer. If this is done the SkDrawable is in charge of adding the required memory
* barriers to the queue for the sampled images since the Skia backend will not do this.
* The VkImage is informational only and should not be used or modified in any ways.
