+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.

+    * If num_semaphores is non-zero, the frontend will wait for the semaphores provided to be signaled
+    * before using the results further in the pipeline.
+    * Using semaphores is optional for synchronization purposes, but if not using
+    * semaphores, an image memory barrier in vkCmdPipelineBarrier should be used in the graphics_queue.
+    * Example:
+    *
+    * vkCmdPipelineBarrier(cmd,
+    *    srcStageMask = VK_PIPELINE_STAGE_ALL_GRAPHICS_BIT,
+    *    dstStageMask = VK_PIPELINE_STAGE_FRAGMENT_SHADER_BIT,

+    *       dstAccessMask = VK_ACCESS_SHADER_READ_BIT,
+    *    });
+    *
+    * The use of pipeline barriers instead of semaphores is encouraged as it is simpler
+    * and more fine-grained. A layout transition must generally happen anyways which requires a
+    * pipeline barrier.
+    *
+    * The image passed to set_image must have imageUsage flags set to at least
+    * VK_IMAGE_USAGE_TRANSFER_SRC_BIT and VK_IMAGE_USAGE_SAMPLED_BIT.
+    * The core will naturally want to use flags such as
+    * VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT and/or VK_IMAGE_USAGE_TRANSFER_DST_BIT depending
+    * on how the final image is created.
+    *
+    * The image must also have been created with MUTABLE_FORMAT bit set if 8-bit formatt are used, so that the frontend can
+    * reinterpret sRGB formats as it sees fit.
+    *
+    * Images passed to set_image should be created with TILING_OPTIMAL.
+    * The image layout should be transitioned to either VK_IMAGE_LAYOUT_GENERIC or VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL.
+    * The actual image layout used must be set in image_layout.
+    *
+    * The image must be a 2D texture which may or not be layered and/or mipmapped.
+    * The image must be suitable for linear sampling.
+    * While the image_view is typically the only field used,
+    * the frontend may want to reinterpret the texture as sRGB vs. no-sRGB for example
+    * so the VkImageViewCreateInfo used to create the image view must also be passed in.
+    * The data in the pointer to the image struct will not be copied
+    * as the pNext field in create_info cannot be reliably deep-copied.
+    * The image pointer passed to set_image must be valid until retro_video_refresh_t has returned.
+    *
+    * If frame duping is used when passing NULL to retro_video_refresh_t,
+    * the frontend is free to either use the latest image passed to set_image or reuse the older pointer
+    * passed to set_image the frame RETRO_HW_FRAME_BUFFER_VALID was last used.
+    * Essentially, the lifetime of the pointer passed to retro_video_refresh_t should be extended
+    * if frame duping is used so that the frontend can reuse the older pointer.
+    *
+    * If frame duping is used, the frontend will not wait for any semaphores.

+    * Knowing this index is very useful for maintaining safe async CPU and GPU operation without stalling.
+    *
+    * The common pattern for synchronization is to receive fences when submitting command buffers

+    * we last saw get_sync_index(). This means we can safely reuse or free resources allocated in this frame.
+    *
+    * In theory, even if we wait for the fences correctly, it is not technically safe to write to the image
+    * we earlier passed to the frontend since we're not waiting for the frontend GPU jobs to complete.
