| On some implementations, setting the |
| ename:VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT on image creation can cause access |
| to that image to perform worse than an equivalent image created without |
| ename:VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT because the implementation does not |
| know what view formats will be paired with the image. |
| |
| This extension allows an application to provide the list of all formats that |
| can: be used with an image when it is created. |
| The implementation may then be able to create a more efficient image that |
| supports the subset of formats required by the application without having to |
| support all formats in the format compatibility class of the image format. |
