Still Images Do Not Render

[NickGenArts]

In the devel branch, the special case code for single images looks for ( timeDomain.min <= kOfxFlagInfiniteMin ) and ( timeDomain.max >= kOfxFlagInfiniteMax ) However, both min and max are set to kOfxFlagInfiniteMin.

The following patch fixes the issue, but I'm not sure it's the best way to fix it.

Ok, this is a bug. "timeDomain.max" should be defined to kOfxFlagInfiniteMax on still images.

I didn't achieve to reproduce it. Could you send a sam-do command line or a python script that shows the problem? Maybe a bug with a particular reader plugin...

Found it. It's only the case with the InputBuffer plugin.
