[Bf-committers] Another interface_draw.c question: vec[7][2]

[Diederick Huijbers | Apollo Media]

Hi,

In interface_draw.c I see a couple of  this arrays that are used to draw 
rounded rectangles;
float vec[7][2]= {{0.195, 0.02}, {0.383, 0.067}, {0.55, 0.169}, {0.707, 
0.293},
                      {0.831, 0.45}, {0.924, 0.617}, {0.98, 0.805}};


I'm wondering where these numbers came from? Probably it's a cached 
results of cos(angle)/sin(angle).
But what angle stepsize is used then?
