dxDrawLine3D, make possible nice connection between each line

[CrosRoad95]

Is your feature request related to a problem? Please describe.
When you want to make 2 3d lines, nicely connected together, you just can't do this

addEventHandler("onClientRender", root, function()
    dxDrawLine3D(-2442.79,731.83,35.02, -2432.79,731.83,35.02, tocolor(255,0,0), 20)
    dxDrawLine3D(-2442.79,731.83,35.02, -2442.79,721.83,35.02, tocolor(255,0,0), 20)
end)

Describe the solution you'd like
my solution is:
skip first start x,y,z in second dxDrawLine3D, and new line will start from last end x,y,z and gap will filed with another line 3d

blue rectangle is new one which would be created

Describe alternatives you've considered

Additional context
This is only cosmetic issue

I feel like this should be left to the persons executing the draw, you know the width and end position of each line. It's not too hard to calculate from there either a square that goes over the corner, or adjust the end points so that they extend to the edge of each other.

As an option it may be a filled circle (it's simpler to calculate, because you have not needed to find the corners, etc)

Is a dxDrawCircle at the intersection point with radius=lineWidth suitable?

Also, love2d has love.graphics.setLineJoin / LineJoin which is nice.

This is their implementation.

half of the lineWidth I guess

I agree, although we could probably publish this calculation as a "useful script" somewhere (as this offset changes depending on the angle between the two lines).

(Actually I don't think an offset is all you need — the miter and bevel options above are not possible with just offsets)

Also, probably only suitable if you want a rounded edge.

I like the idea of it being a useful script, and yeah the love2d options look very nice.

I propose adding additional arguments to the end of dxDrawLine3D. One argument which is a string for the LineJoin mode, and then support an infinite number of subsequent points.

Old

bool dxDrawLine3D ( float startX, float startY, float startZ, float endX, float endY, float endZ [, int color = 0xFFFFFFFF, float width = 1.0, bool postGUI = false ] )

New

bool dxDrawLine3D ( float x1, float y1, float z1, float x2, float y2, float z2 [, int color = 0xFFFFFFFF, float width = 1.0, bool postGUI = false, string lineJoin = "miter", float x3, float y3, float z3, ... ] )

And do the same for dxDrawLine I guess, but probably as a separate PR/issue.
