Oh dear... thanks for digging that up.
I didn't know the web had a standard for alpha. Certainly
0xAARRGGBB
has been used in windows code for as long as I've been
programming...
but now there's a competing #RRGGBBAA version...
How to resolve this? I guess, go with the web? I should probably
change it to the CSS4 way.
My idea is still to use a template:
colorFromString!"rgba" or colorFromString!"argb" (please notice
that AFAIK, the second most used way is actually "abgr" rather
than "argb" - because of byte-order)
And I think it's a good idea to set template argument to some
default.
MS is not sure about this, anyway.
