Syntax: $height(text,font,size)

When writting to a window using draw commands pixels come into play now depending on the actual font its pixel maps could be drawn differently from a simple ARIAL font to a Custom font such has Chicken Scratch. If you go to a simple paint program and different between the font #'s and the font themselves youll see that some can be read and some can hardly be read and some are different sizes when talking about height. Now the Text position of this field ask to put any data you want (treated has plain text) as if you were doing this in a paint program with font editor, then pixel wise.. it ask for the font name, and the size of the font so you can know the Pixels CEILING height or length vertical known has Y, remember your X,Y's? AND NO they are chromosomes... lol

Font, no explanation needed use any font you want to determine it's """PIXEL""" size

Last but not lease it's size (this becomes a variable) using $height(text,arial,14) has the same height properties has $height(text,arial,13) has pixel wise talking it has a different that is too minimal for it to be smaller then box 14 or larger then 13 now if you go to size 15 the value changes. Now on custom font's value 14 arial might be different size on chicken scratch 14.

So long story short the TEXT value is for the program (mirc) to realize it has to test something, just like when you use a PAINT program you wont know the SIZE till you enter data into the shiny little box.
