CPTBorderedLayer renders offscreen

[GoogleCodeExporter]

setMasksToBorder: uses self.mask = maskLayer which makes it "yellow" in the 
simulator/device and means a serious performance hit, says Josh Shaffer 
(@joshshaffer on Twitter).

What steps will reproduce the problem?

I guess just add a Core Plot to a UIView, no? :-) Can you reproduce it.

What is the expected output? What do you see instead?

I'm expect to perform better, so it means not use a mask on the layer :) 
Commenting that one self.mask = ... my code still works (probably because I'm 
not using borders for example).

What version of the product are you using? On what operating system?

Working on it. I have an idea how to fix it, but I haven't finished 
implementing and testing the fix yet.

After further investigation, I am unable to remove the layer mask from the plot 
area frame. It is required in some cases to get the desired clipping behavior 
for axis labels and other parts of the graph.

I wasn't able to find an efficient way to dynamically manage the mask so it is 
used only when needed, so for now, you'll need to manage the mask manually.

When the mask is not needed, set masksToBorder to NO on the plot area frame. I 
updated all of the example apps to remove the mask when it is not needed.
