+
+NOTES:
+
+Geometry:
+---------
+
+"IU" = the size of an item in inventory units.  For most things, scaling is
+done such that 64 pixels in the image fits exactly 1 IU, though 1 IU in the
+formspec doesn't necessarily correspond with any specific number of screen
+pixels (but that's not important here).
+
+Minetest normally uses exact values for sizes, but due to legacy screwiness in
+how formspecs are rendered, positioning is done at a scale of about 1.2422:1
+in the horizontal direction, and 1.1538:1 in the vertical direction, at least
+for most stuff, and some stuff isn't exact-size either.
+
+Furthermore, Minetest doesn't treat the upper-left corner of a formspec as
+the (0,0) origin, but rather, somewhat below and to the right of that spot
+(officially it's off by (0.5, 0.5) IU, but in reality, the offset is closer to
+half of that).
+
+A 1x1 IU label/graphic that should be displayed at position (2,2) will end up
+being 1x1 in size as intended, but positioned at about (2.484,2.308) plus the
+origin point.
+
+The Minislots display engine will position the imagery to such that there's a
+thin shaded border around the machine's graphics, and it will correct for the
+above-mentioned legacy scaling and positioning where it can.
+
+The upper overlay, reel underlay, and line win overlays are 939x704 px	--> 14.6667 x 11 IU
+The lower overlay image is 939x128 px									--> 13 x 2 IU
+A single reel image is 128x576 px										--> 2 x 9  IU
+
+A digit glyph is 48x80 px, or 0.75 IU, but will be displayed at 75%, 45% or 40%
+of that IU size, depending on line height (to fit in large values)		--> 0.563, 0.338, or 0.30 IU
+The "Bal", "Bet" and "Win" labels are 128x80 px, but should be narrower	--> 1.125 x line-height IU
+The "Line Win" label is 256x80 px, should be displayed at 50% width		--> 3.0 x screen_line_height_3 IU
+A colon or parenthesis is 24x80 pixels, displayed at 50% digit width	--> 0.188 x screen_line_height_3 IU
+The "Scatter Win" is 384x80 px, should be displayed at 50% width		--> 3.0 x screen_line_height_3 IU
+The "Bonus Win" label is 352x80 px, should be displayed at 50% width	--> 2.75 x screen_line_height 3 IU
+The cash slot is 320x128 px and is normally shown at full-size			--> 5.0 x 2.0 IU
+
+Note that the cash slot can be almost any size/shape and can be placed
+anywhere, so that you could, for example, draw it to look like a coin slot,
+with all the chrome and corrugated edging and such, and position it at the top
+of the form, to mimic turn-of-the-century-styled machines.  That said, bear in
+mind that when you click on it, you're taken to the "cash intake" screen,
+where the cash slot image is also shown, at the same size, and in there, it
+has to fit in between the single intake slot and the inventory slots.
+
+The "screen" in the lower overlay is 384x112 px, or 6.0 x 0.875 IU.
+
+The currency label is 96x80 px, and if printed, is positioned 25% of a digit's
+width after the end of the amount.  It is scaled to the 1.333 times a digit's
+width to keep it's relative scale correct.
+
+The "Win" label, if printed, will appear half a digit glyph's width after the
+Bet amount's currency label.
+
+Balance, Bet, Win, Scatter Win, and Bonus Win amounts are printed immediately
+next to their labels.  Be sure you leave a little space on the right in the
+images, as needed.
+
+The scatter and bonus highlight boxes are displayed at 1.333 times the width
+of the reel, and positioned 1/6 reel width above and left, thus centering it
+over the symbol.  This is to allow some kind of "glow" or other effect to
+appear just outside of the highlight box itself.  The nominal size of the
+image is 171 px square, but because Minetest does not support full alpha on
+overlaid images in a formspec, you'll have to fake it by dithering the alpha.
+Draw this image large enough and the downscaling will blur the dithering,
+making it look like real alpha, mostly.  That is why the images in this
+machine are drawn at 512 px square.
+
+The various labels, parenthesis, and colon were drawn with The GIMP using the
+"Liberation Sans Narrow Bold Condensed" font, 85 point height, with the inter-
+character spacing set as small as the wording would allow (usually -4.0).
+Anti-aliasing enabled, "Full" hinting.  Text positioned two pixels from the
+left, baseline at 60 (so the lower left corner of the "B" in "Bal:" is at
+(2,60) according to GIMP).
+
+The numerals use "Century Schoolbook L Bold" font, same size, settings, etc.
+Same vertical positioning, and horizontally-centered`.
+
+Reels always show three symbols' of height, not counting the overlap at the
+top and bottom to allow for symbols to be positioned "off-screen".

+
+How wild cards work:
+--------------------
+
+[WILD!] is basically "don't care", as far as the engine's concerned, and will
+match the highest entry in the table that can theoretically form a match,
+regardless of how many symbols actually match.
+
+For example, suppose you get a normal-looking spin showing
+[WILD!][77][77][lemon][cherry] on a line.  That won't match anything, because
+there's no match line that only needs one symbol, nor any match lines that
+allow for a match consisting of only three "7" symbols of any kind.
+
+On the other hand, suppose you get [WILD!][WILD!][WILD!][2bar][cherry].  Sounds
+like it should match the {"2bar", "2bar", "2bar", "2bar", nil} entry, but
+it'll pick the {"3bar", "3bar", "3bar", nil, nil} entry, because that one also
+matches, but it's worth more.
+
+This extends to as many reels as the machine has, and as many [WILD!]'s as
+there are in a pay line, regardless of where in the line they appear (so long
+as the symbols that precede and follow the [WILD!]'s can form valid matches,
+of course).
+
+A pay line consisting of all [WILD!]'s is equivalent to whatever the highest
+winning combination is in your machine (five [JACKPOT]'s here).
