Attribute for `<SPACER ...>`
`SIZE = integer`

SIZE gives the horizontal size for the space when you use HORIZONTAL, and vertical size when you use VERTICAL. Why didn't they just use the WIDTH and HEIGHT attributes? Apparently that would have just made too much sense.

this code produces this

There was a long <SPACER TYPE=HORIZONTAL SIZE=50> pause<BR> and then he <SPACER TYPE=HORIZONTAL SIZE=100> spoke.
There was a long pause
and then he spoke.

hi there! <SPACER TYPE=VERTICAL SIZE=50> hi there! <SPACER TYPE=VERTICAL SIZE=200> hi there!
hi there! hi there! hi there!
