Purpose and Motivation

Fixes the following problems

• ServerTreeView: fix "group rect issue" and "node visibility issue" of #6294, fix "Rect collision issue with too many nodes" #6834 (comment)

• ServerTreeView: fix "group rect issue" and "node visibility issue" of #6294, fix "Rect collision issue with too many nodes" #6834 (comment)

The commit for resolving the problem in #6834 is problematic due to its complicated structure; there are too many if clauses, which makes it very complex and confusing. In this implementation, I reinstated the algorithm from before #6834 and made a few minor changes to the countSize function. While not perfect, this is a significant improvement on my previous implementation.

To test extreme cases

• Evaluate multiple times the following code block, or
• Change ! 15 to ! 100 or ! 202

(
{ Group(s) } ! 2;

{}.play;

x = {
	s.bind {
		g = Group(s);
		{
			var h = Group(g);
			{ Synth(\default, [\amp, 0.0001], target: h, addAction: \addAfter) } ! 4
		} ! 15;// ! 100 

		{}.play;
	};
};

x.();
s.meter;

s.freqscope;

s.scope
)
