And similarly for differences in plori results when run before or after plinit which is why I have reverted your recent changes to x03 and x03.tcl. I think we just have to accept that certain C examples do special commands before plinit so there is no way to mimic that exact behaviour when we use just one plinit for a whole string of examples as in examples/tk/standard_examples(.in). So the goal for the string of examples should be that they look reasonable rather than exactly the same as in the C examples. > > That makes it impossible to include x16 in this test: plinit is run > first and then the examples are run.

I would leave it and example 3 in and just accept that you will get a different result for examples/tk/standard_examples(.in) than the corresponding C example because of the pre-plinit shenanigans in the C example. Of course, for the individual runs of the Tcl examples, we have been able to arrange complete consistency with the C results because we have full control there to do anything we like before plinit. But that is not the case for examples/tk/standard_examples(.in). The test_tk_standard_examples target (which is run as a prerequisite for the test_interactive target) no longer works because of some recently introduced regression that I am still tracking down (it is not just the recently introduced xwin.c changes, but something else as well). But from my memory of previous results, we need colour restoration at the end of each plot in examples/tk/standard_examples(.in) to get reasonable looking results. So I hope you will be able to implement a restoration procedure (that at least restores colours to default) in Tcl so that we can invoke that procedure after each example in examples/tk/standard_examples(.in).
