Trace Hint / Trace Render Modifications

[seveibar]

• * The tracehint should NOT draw the trace- the trace should draw the trace #41
• * The tracehint should show the width that the trace will get at each offset and the user should be able to "click and drag" to make the trace thicker in the pcb viewer
• * The tracehint should have mixed-blend-mode: difference, same as the dimension overlay as shown in the code screenshot below
• * There should be two circles on a trace hint when the trace_width is defined. One circle corresponds to the trace_width at that offset. If the trace_width isn't defined- the user hasn't specified their desired width at that point
• * This is not needed for the initial PR, but there should be a square that the user can click and drag to adjust the trace_width, when they click and drag the square, it emits an "EditEvent"

we're getting closer- I didn't have a design totally in mind when we started so I can do a bit better next time, the only thing I knew is that we wanted to support interpolated traces, but I didn't realize we were editing the trace hint this time because of the same color etc.

Here are some pull requests that might be helpful reference for this task:

• feat: trace_width option added

@seveibar Currently, this is how the soup looks like when you build your circuit and add a trace_hint with the offsets. And this is visible when you click on the Edit trace button. Going forward we will be adding the offset route props for the trace and not trace_hint with the route thickness mode and it will be only visible when you click Edit trace button like now. Is this correct?

Or the trace will always be visible in that polygon shape and only the trace_hint will be visible on clicking the Edit trace button

Yes the trace should always be visible in the polygon shape

Going forward we will be adding the offset route props for the trace

We won't add offset for a trace. A trace hint is used to generate a trace inside of tscircuit/builder and should keep the offset prop

route thickness mode

Trace's should have a route thickness mode, not a trace hint. It's not totally clear how the props for this will look but probably like this:

<trace thicknessMode="interpolated" from=".R1 > .left" to=".R2 > .right" />

This might be a duplicate of: Trace Hints should allow specifying a trace width.
