Compiler error with the feature, image

[IGreyGooI]

How to reproduce:

compile a empty binary crate with the following dependency
vek = {version = "0.15", features = ["default", "image"]}

get compiler error when cargo check

Hi, thanks for the report. It appears I had increased the image dependency's version to latest at some point, but I was a bit too confident that it would still compile. Sorry about that.

The fix has been published as version 0.15.3. Please let me know if you encounter any issues, or have any remarks or comments!

Thanks,

[yoanlcq]

Btw, please be careful not to use the Pixel trait on vectors where T is anything other than u8 and u16; otherwise, the COLOR_TYPE will give wrong information.

I didn't see this as a problem back then, because one could specify the bit depth procedurally.
A real "safe" fix would be to implement Pixel only if T is u8 or u16, but that's a bit involved and is a breaking change; so I'd rather delay working on that, until someone does complain.

Thanks,
