I added this demo to verify the detailed support of Path drawing in
GPUI.
Because of, when we actually used GPUI to draw a 2D line chart, we found
that the straight line Path#line_to did not support `anti-aliasing`, and
the drawn line looked very bad.
As shown in the demo image, if we zoom in on the image, we can clearly
see that all the lines are jagged.
I read and tried to make some appropriate adjustments to the functions
in Path, but since I have no experience in the graphics field, I still
cannot achieve anti-aliasing support so far.
I don't know if I used it wrong somewhere. I checked `curve_to` and
found that the curves drawn have anti-aliasing effects, as shown in the
arc part of the figure below.
