NOTE: My changes are to the Quick Reference found at my web site,
http://www.donovansweb.com/~chaffe/quickref.html .
I believe someone with the moniker "ingo" is in charge of modifying the
distributed documentation. ;-)

I have added one of my peach colored notes below the DOT_ITEM syntax:
The hf item may be used only in a user-defined function.

Tsk, tsk. Copy-Paste error. In the FN_FLOAT_FUNCTION list I now have:
max (FN_FLOAT,FN_FLOAT[,FN_FLOAT]...) | min
(FN_FLOAT,FN_FLOAT[,FN_FLOAT]...)
Note that I use FN_FLOAT to distinguish it from the other FLOAT that is not
quite the same as the one for user-defined functions.

Didn't know we could use it. See modifications below.

Well, I didn't know that either. I have changed the FLOAT_USER_FUNCTION
syntax, the pattern part, to the following:
function { pattern { PATTERN [PATTERN_MODIFIERS] } }
I have also modified the PATTERN syntax to look like this:
MAP_PATTERN | brick [BRICK_ITEMS] | checker | hexagon | object
{ LIST_OBJECT }
The same change was made to the appropriate BITMAP_IMAGE items. That would
be in section 10.1.10.8 Pattern Modifiers in the docu.
Thanks for finding these. Let me know if anything else needs to be
corrected.
