[WINGLESS] Perfect Rounded Rectangle using WINAPI+MSAA !!

[color=#FF0000]Perfect ??? As some of you know, the usual RoundRect function which uses arcs and ellipses to draw roundrectangles is not very efficient. Artifacts can be seen everywhere, and AA sucks with it. The top left rounded corner is fine, but the rest of them far from fine. So much that the bottom right seems completely dishtinguishable from the top left. Now this is not symmetrical and human eye praises symmetry so, they are bad. Most of the time you will find yourself compromising to the situation but no more ! [color=#6B8E23]MSAA+WinAPI to the rescue [color=#FF4500]What is this MSAA ? [color=#1E90FF]MSAA is a method of anti aliasing used to smooth out jagged lines. In this method, the target image is rendered at a higher resolution than normal, and the shrinked to the original size. Downscaling largely removes aliasing, and the render resolution is, smoother is the image. [color=#FF4500]WinAPI ? [color=#1E90FF]I saw a function in WinAPI that produces roundrects. Named CreateR

Why are you dividing by 1?

Never knew how MSAA worked so thanks a lot for the concept.
