I notice that both Tcl::Tk and Tcl::pTk have some tests that currently require the Img extension to handle image formats not included in Tcl/Tk. Would it be desirable to still test the formats that are available (gif; png on Tk 8.6), or is the test more about exercising the capabilities in Img? Is it even possible to plan a certain number of tests and then skip a subset of them?
This is low/“wishlist” priority; I ask only because at the moment MacPorts doesn’t have the Img extension.
