These are currently hard coded to '//' and '#'. The code is there to return
them to the caller but currently they are thrown away.
Should add a skip_comments option and allow customisable markers.
An image rotate operation creates a new image with the same dimensions but with
the contents rotated by an angle around the centre of the image. Also added a
script object to float function to allow this.
Allows execution of unary operations: Pre/postfix inc/decrement, logical
negation and unary plus/minus.
The writebacks of increment/decrements happen during the execution of the
expression, unlike C where they are executed after the line if executed. This
is the case simply because it is simpler to execute this way.
This is an initial support for the scripted plugin. There are _many_ FIXMEs
and the whole code is reather unstable. The formatting is completely incorrect
and will be changed soon. There are scripts which are converted using a perl
to an C embeddable string.
