-Negative numbers still screw it up... Need to think about what we're
-trying to do here. The fact that it worked with 72 seems to have been pure luck.
-It seems the problem is negative numbers: We can't let that happen.
-When taking away the zero, it pops over 1 px at zero, then goes about 1/2 a
-grid at x<0.
-
-The bitmap looks like this:
-
-+---+---+---+---+---
-| | | | |
-| | | | |
-+---+---+---+---+---
-| | | | |
-| | | | |
-| | | | |
-
-@ x = 1, we want it to look like:
-
--+---+---+---+---+---
- | | | | |
- | | | | |
--+---+---+---+---+---
- | | | | |
- | | | | |
- | | | | |
-
-Which means we need to grab the sample from x = 3. @ x = -1:
-
----+---+---+---+---
- | | | |
- | | | |
----+---+---+---+---
- | | | |
- | | | |
- | | | |
-
-Which means we need to grab the sample from x = 1. Which means we have to take
-the mirror of the modulus of gridPixels.
-
-Doing a mod of a negative number is problematic: 1st, the compiler converts the
-negative number to an unsigned int, then it does the mod. Gets you wrong answers
-most of the time, unless you use a power of 2. :-P So what we do here is just
-take the modulus of the negation, which means we don't have to worry about
-mirroring it later.
-
-The positive case looks gruesome (and it is) but it boils down to this: We take
-the modulus of the X coordinate, then mirror it by subtraction from the
-maximum (in this case, gridPixels). This gives us a number in the range of 1 to
-gridPixels. But we need the case where the result equalling gridPixels to be
-zero; so we do another modulus operation on the result to achieve this.

likely we can just rely on the object itself and steal its state like we have in the commented out portion below; can prolly rewrite the HitTest() portion to be one line: needUpdate = HitTest(cObj, point);
Well, you could if there was only one object in the Container. But since there isn't, we have to keep the if HitTest() == true then needUpdate = true bit. Because otherwise, a false result anywhere will kill the needed update elsewhere.
