| The +VK_KHR_8bit_storage+ extension allows use of 8-bit types in uniform and |
| storage buffers, and push constant blocks. |
| This extension introduces several new optional features which map to SPIR-V |
| capabilities and allow access to 8-bit data in code:Block-decorated objects |
| in the code:Uniform and the code:StorageBuffer storage classes, and objects |
| in the code:PushConstant storage class. |
| |
| The code:StorageBuffer8BitAccess capability must: be supported by all |
| implementations of this extension. |
| The other capabilities are optional. |
