| imagebox: Don't try to scale by infinite (FS#1248) |
| |
| When an imagebox was drawn with width or height zero, it tried to calculate the |
| needed scale factor for making the image fit. Sadly, this would be a division by |
| zero aka infinite in this case. |
| |
| Fix this by just not drawing anything if there is no space available. |
