Tokens are every bit of code in a scene: every keyword are tokens, any
variable and operator is a token, a numerical value is also a token...

And why do you ask the exact same question again after three weeks?

Since the POV-Ray SDL is a turing-strong language, it's impossible
to predict in a general case how long it will take to parse and thus
show a percentage of how much has been parsed already (this is basic
computational theory).
On the other hand, if POV-Ray shows no sign that it really is doing
something, it may look like it has hanged because nothing seems to be
happening.
As a compromise POV-Ray shows the number of tokens it has parsed
so that the user gets visual feedback that it really is doing something
and how much it has done already.
