The corners are too sharp

How is it now

The end of the curve is rough.

Proposal: softer corners

iirc, i've noticed this as well. i believe that roundness of corners may be improved for gl-powered backends (glx, egl), but they'll still be sharp on the xrender backend due to the x render extensions being not very flexible.

@tryone144, take a look, maybe?

[absolutelynothelix]

thinking about this i've tried to reimplement rounded corners using squircles (as suggested in #609). i believe that it looks better. however, it's just a quick and dirty prototype (can't get it working well because i'm bad at opengl).

[absolutelynothelix]

@yshui, @tryone144, what do you think about using squircles for rounded corners by default?

my work on this is available at absolutelynothelix@cac526a, but i can't make it friends with blur (and probably it's not well done because i'm bad at opengl and shaders), so i hope someone will pick it up if it'll be considered a good idea.

Thank you for the patch, it still works on the latest commit. My corners looks beautiful now!
