FONT TRANSFORMATIONS
Get character width - SM_CharW()
Get string width - SM_StrW()
Draw character - SM_Char()
Draw string - SM_Str()
Draw icon (character mask) - SM_Icon()
Entry: msgBytL0, a character value or string length
msgPtr, ^string
Notes: The character or string is drawn or has its length calculated
using the window's current font information. This means those
font face, font style, and font scaling factors are used.
The icon or icon mask is drawn using the text scaling factors.
I.e., scaling to double the character height causes the icon
to also be doubled in height. Font face and font style, how-
ever, have no influence on the icon output. Since all icons
and icon masks are the same width, txIconW() simply returns
the width of any icon or icon mask scaled using the text scal-
ing.
Characters and icons use a drawing verb similar to the drawing
modes of shapes. The difference is that framing modes are
ignored.
