+Here we set the grid size in pixels--12 in this case. Initially, we have our
+zoom set to make this represent 12 inches at a zoom factor of 25%. (This is
+arbitrary.) So, to be able to decouple the grid size from the zoom, we need
+to be able to set the size of the background grid (which we do here at an
+arbitrary 12 pixels) to anything we want (within reason, of course :-).
+
+The drawing enforces the grid spacing through the drawing->gridSpacing variable.
+
+ drawing->gridSpacing = 12.0 / Global::zoom;
+
+Global::zoom is the zoom factor for the drawing, and all mouse clicks are
+translated to Cartesian coordinates through this. (Initially, Global::zoom is
+set to 1.0. SCREEN_ZOOM is set to 1.0/4.0.)
+
+Really, the 100% zoom level can be set at *any* zoom level, it's more of a
+convenience function than any measure of absolutes. Doing things that way we
+could rid ourselves of the whole SCREEN_ZOOM parameter and all the attendant
+shittiness that comes with it.
+
+However, it seems that SCREEN_ZOOM is used to make text and arrow sizes show up
+a certain way, which means we should probably create something else in those
+objects to take its place--like some kind of scale factor. This would seem to
+imply that certain point sizes actually *do* tie things like fonts to absolute
+sizes on the screen, but not necessarily because you could have an inch scale
+with text that is quite small relative to other objects on the screen, which
+currently you have to zoom in to see (and which blows up the text). Point sizes
+in an application like this are a bit meaningless; even though an inch is an
+inch regardless of the zoom level a piece of text can be larger or smaller than
+this. Maybe this is the case for having a base unit and basing point sizes off
+of that.
+
+Here's what's been figured out. Global::zoom is simply the ratio of pixels to
+base units. What that means is that if you have a 12px grid with a 6" grid size
+(& base unit of "inches"), Global::zoom becomes 12px / 6" = 2.0 px/in.
+
+Dimensions now have a "size" parameter to set their absolute size in relation
+to the base unit. ATM, the arrows are drawn in pixels, but also scaled by
+Global::zoom *and* size. Same with the dimension text; it's drawn at 10pt and
+scaled the same way as the arrowheads.
+
+Need a way to scale line widths as well. :-/ Shouldn't be too difficult, just
+need a thickness parameter similar to the "size" param for dimensions. (And now
+we do! :-)

+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.
