Description
During discussion of Issue #998, it was discovered that using FixedAreaConstraints.MinWidthPercent on a tree without columns would lead to an infinite loop inside TVTHeader.ResizeColumns
While this is fixed in the current source, the same infinite loop arises if the tree has one more columns but none having coFixed in its options.
In this case, RangeEndCol is greater than 0 but MaxDelta stays at 0 because column options are not matched to the passed in expected values.
Yes, I agree that it's a bit "stupid" to have set FixedAreaConstraints.MinWidthPercent when non columns are fixed, but this should not lead to an infinite loop as changing the column options may happen during the life of the application, not necessarily at design time.
Here is a sample application showing the issue:
Beware! Opening the main form unit will deadlock your IDE if you have installed the design package, as it will try to run the affected code.
