Syntax was: buffer(name=bla,alpha=bool);
Changed to: buffer:bla(alpha);
There's a semicolon between buffer and its name because ALL whitespaces
are discarded. This might prove useful sometime in the future, so let's
keep it this way for now :)
Padding was brutally calculated by suming ALL the filters'
individual paddings. Now we try to be a bit smarter and propagate
the padding between buffers in the filter chain.
So, the (font) effects will be described by a string. It's
basically a new language (yeah yeah sorry), VERY simple, based
on function calls a la Python, with sequential and named arguments.
This string is intended to be passed directly to an evas text object
and embedded into the evas textblock's markup tags.
This file implements both the basic parsing functions, the
compilation of instructions into a queue of commands, and the glue
code for the rest of the filter infrastructure.
