Summary
This PR is about overhauling, cleaning, and improving Shape drawing in ShapeEngine. The main goal is to fix all outline drawing functions of closed shapes and Polyline drawing.
I am implementing custom algorithms to construct and draw triangles instead of just drawing lines with cap types. Currently, using colors with any transparency for outlines will look bad on almost all shapes (line, ray, segment are not affected). Every other shape will have overlaps in the corners that will become visible with alpha values below 255.

Affected Functions
Below is a list of functions that are affected by this problem and need to be fixed (might be missing some functions):
At first, I did not realize how much work it would be to do this, and I just started working on this. Thankfully, I am close to the end now with most of the functions already working. Still needs complete testing to make sure all of this works!
Performance
This should (theoretically) come with performance improvements on a lot of drawing functions because they are now drawing much fewer triangles than before. The downside is that the function itself needs to do more work to calculate all the triangle points needed. I will test it once I am finished.
