shape frames not set properly in setup{}

[traviskirton]

in the setup method, when a shape is created, it takes longer to build the path than to set its new center position...
so if i write

shape = [C4Shape rect:];
shape.center = CGPoint;

the shape stays in its original rect...

not sure how to get around this...

[traviskirton]

this is a general problem that i don't know yet how to get around...

a similar issue with initialization happens when you try to call [shape closeShape] right after initializing like the following:

---

[shape rect:...];
[shape closeShape];

[traviskirton]

Fixed this for most shapes...
Haven't fully tested with arcs and curves though...

The following works:

#import "C4WorkSpace.h"

@implementation C4WorkSpace {
    C4Shape *r1, *r2;
}

-(void)setup {
    CGPoint points[4] = {CGPointZero, CGPointMake(100, 0), CGPointMake(0, 100), CGPointMake(100, 100)};
    r1 = [C4Shape line:points];
    r1.center = self.canvas.center;
    [self.canvas addShape:r1];

    r2 = [C4Shape rect:CGRectMake(0, 0, 40,40)];
    r2.fillColor = [C4RED colorWithAlphaComponent:0.5];
    r2.lineWidth = 0.0;
    r2.center = self.canvas.center;
    [self.canvas addShape:r2];
}
