Image should not take bc.max() when only width bounded.

[JAicewizard]

Currently the Image widget takes bc.max
This means what when you want to have images in a scroll-able horizontal list, the height of the images is +inf .
This means that the images are not displayed at all.
When the image is width bounded the image should take into consideration the width/height of the image itself and calculate the correct height from that.

The same should probably be done to height constrained image widgets.

I could probably implement this, its not that hard.
If this is accepted I will start working on it.

Without looking at it hard I 100% believe you're correct, bc.max() is rarely the correct constraint.

I redid the calculations for the size, I tried making a test for this but the problem is that I need to set the size to +inf.
But the harness makes a creates an bitmap with the given size. Since we cannot make a bitmap with infinite size this obviously fails.
A possible solution would be to only create the bitmap after the layout has been done.

I will test this in an actual application, if that works I will create a PR.

I tried looking into the harness code, but it seems to be tightly integrated with the root window, so maybe that is left for someone who knows more about this.

I managed to get the test working using just scroll as the root widget.
