Unsupported image format on Star Swarm

[libcg]

I'm currently working on GRVK which implements the Mantle API over Vulkan. The Star Swarm demo partially runs, however the game is trying to create images with the following properties:

• format: VK_FORMAT_R32_UINT
• type: VK_IMAGE_TYPE_3D
• tiling: VK_IMAGE_TILING_LINEAR
• usage: VK_IMAGE_USAGE_TRANSFER_SRC_BIT | VK_IMAGE_USAGE_TRANSFER_DST_BIT | VK_IMAGE_USAGE_SAMPLED_BIT | VK_IMAGE_USAGE_STORAGE_BIT

AMDVLK doesn't support that combination, however 1D and 2D seem to work. I'd like to know if this could be fixed.

Edit: updated the usage flags as they were incorrect.

I write a simple code to create an image with your create-info in vkcube, there is no error. Could you give more detail about your demo code?
