/* There are a couple of concepts of "coordinates" in this file.
- DIW coordinates
- DDF coordinates (essentially cycles, resolution lower than lores by a factor of 2)
- Pixel coordinates
* in the Amiga's resolution as determined by BPLCON0 ("Amiga coordinates")
* in the window resolution as determined by the preferences ("window coordinates").
* in the window resolution, and with the origin being the topmost left corner of
the window ("native coordinates")
One note about window coordinates. The visible area depends on the width of the
window, and the centering code. The first visible horizontal window coordinate is
often _not_ 0, but the value of VISIBLE_LEFT_BORDER instead.
One important thing to remember: DIW coordinates are in the lowest possible
resolution.
To prevent extremely bad things (think pixels cut in half by window borders) from
happening, all ports should restrict window widths to be multiples of 16 pixels. */
