Option for component shadow

[noloop]

I think that one big differencial in one GUI component be the shadows. Example:

https://www.w3schools.com/cssref/tryit.asp?filename=trycss3_box-shadow2

This example is exagerated, but "small shadows" be nice, the google desgin really like to use the "small shadows", so if you have an android you already have seen it.

how would i do this in Nuklear? Is it possible, if not yet, how difficult it would be to implement something like this?
