Title: Preprocessor now accepts whitespace after height (fixes #2924)

As @benfry said, there was a missing white space after second match group.

Test with online tool looks good (check matches in the right column): http://regex101.com/r/sP8rI1/1
Spaces around renderer are trimmed in the preproc code later.
