/** Generate all mipmaps for a given texture down to a 1x1 pixel.
*
* Uses the GPU blit command from one mip level to the next, thus the base mip
* level data must have already been transfered to the image and the image is
* expected to be in VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL. This includes any
* array levels.
*
* \param device The device owning the command buffer.
* \param cmd The command buffer to which the barrier and blit commands
* will be written.
* \param image The image to be processed. All array layers of the base mip
* level must be initialized and in "transfer dst optimal"
* layout. All remaining mip levels must be in "undefined"
* oayout.
* \param mips The total number of mip levels of the processed image.
* \param width The pixel width of the base image.
* \param height The pixel height of the base image.
* \param layers The number of array layers in the mbase image.
*
* \note The processed image will be in "shader read only optimal" layout on
* completion.
