Also, I like your nickname. It's much better...now that I've changed it.

Personally I liked "joew" seeing as it is the *ultimate* first name plus last initial.

Well, I was going to go for [Joe the:Objective c:Lover] but it wouldn't accept that.

In time the project grows, the ignorance of its devs it shows, with many a convoluted function, it plunges into deep compunction, the price of failure is high, Washu's mirth is nigh.

So am I.... this change actually introduces a compile error for some wtf reason:

[source lang="cpp"]// Original
Rectangle& operator=(const Rectangle& rhs) : left(rhs.left), bottom(rhs.bottom), right(rhs.right), top(rhs.top) {}

// Replaced with
Rectangle& operator=(const Rectangle&) = default;
[/source]

EDIT: and yeah it's just a pod struct

If you're going to do one assignment operator, you should do both (move and copy).

As an additional note: VS2012 does not support default nor deleted

I do :)

Gross! I'll stick with clang which has the majority of the standard in smile.png

EDIT: FYI the issue was just that another class using Rectangle didn't have operator= defined ... that's nice it makes it easy to track down during a cleaning day like today
I once used negative array indices in combination with a semi-Duff's Device - and winced in mixed horror/pride afterwards. But it was in the days when C-abuse like that used to please me (I've sinced learned).

Statements like this make me smile:
if ((time = (newtime = GetTime ()) - oldtime) > 0)

Wouldn't do it in real code, but it gets a "hey! you can do this!" comment in stuff I'm fooling around with.

Direct3D has need of instancing, but we do not. We have plenty of glVertexAttrib calls.
