Draw arcs, arcs are not smooth, please confirm whether you can support arcs to be more smooth about graphics-smooth

Don't you get the same results with PIXI.Graphics? The number of segments the arc is build from is defined by PIXI.GRAPHICS_CURVES._segmentsCount.

@dev7355608 This is helpful info. However I noticed that when I call drawRoundedRect or drawCircle, the method now called Graphics.curves._segmentsCount is never called. Is there a way I can make it work for these two methods?

Update: after some digging, I realized that the key is in this part,

graphics-smooth/src/shapes/CircleBuilder.ts

Lines 67 to 68 in 93493e1

	const n = Math.ceil(2.3 * Math.sqrt(rx + ry));
	const m = (n * 8) + (dx ? 4 : 0) + (dy ? 4 : 0);

where the number of segments is determined solely by the radius. However such an approach fails to consider coordinate transformations. If the local coordiantes are scaled up a lot, the circles will have relatively small radii, leading to very few segments and bad result. Could you guys do something about this? (My current workaround is to apply additional scaling down on those circle and increase their radii respectively.)
