Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.

It is absurd. Rather have it medieval-style: "The tangent of the skewed angle equals the tangent of the normal angle multiplied by the ratio width over height." "If two arcs join correctly … XDrawArc does not draw a pixel more than once."

The following bug has been reported to the Debian BTS 2 months ago by Kevin Ryde. Brice On a tty, the eqn math bits in "man XDrawArc" come out looking like [x+wi2th,y+hei2ht] or 2n for normal-angle in the range [32,2n] which makes it pretty hard to understand. Apparently gnu eqn and/or nroff aren't interested in trying to render maths on a tty. It'd be nice if XDrawArc could have alternative bits (".ie n" conditions) that come out better, "[x+width/2,y+height/2]" and "[3*pi/2,2*pi]" etc.
