samples/simple-sphere.rb crashes

[wasnotrice]

This looks like some missing argument parsing for image:

I do have the same issue.

[PragTob]

This is basically #292 - e.g. the image use here oughts to create a new image given dimensions and a block. The sample uses this over and over again to paint things.

This is one of the more under used shoes functionalities afaik and I don't think it needs to be in the alpha (not even the rc..) moving it to 4.1 for now.

Please do argue for this feature if you want it in alpha/rc over at #292 !

It crashes in Shoes 3.2 but only for 64 bit architecture (blur) and it's totally undocumented in shoes what the filters do. It way down my list of things to fix for 3.2 and I've spent a lot of gdb keystrokes trying find it.

There are two issues in the sample. Blur doesn't work, and the shape changes self, so you have to define the app ( app = self ) and call things like app.oval inside the shape blocks.
