I've always preferred "up" mapping to an increase the y-axis value. After reading up on Sparrow and poking around the code (I just started with the framework), there doesn't seem to be support for this out-of-the-box. Is that true?
Nevertheless, it looks like a very small change to get "up = increase y-coordinate" working:
In SPRenderSupport.m, changing
[SPRenderSupport setupOrthographicRenderingWithLeft:0 right:mWidth bottom:mHeight top:0];
to
[SPRenderSupport setupOrthographicRenderingWithLeft:0 right:mWidth bottom:0 top:mHeight];
Does anyone see anything wrong with this adjustment? Might there be any unwanted side effects?
Obviously, I'd prefer not to make changes in my local sparrow project. Is there a way to make this adjustment from my own code?
