text rotate

[MichalPP]

would it be possible to add rotation of text?

SVG output was fairly easy with something like setAttribute('transform', 'rotate(-45)'), but PNG output is fairly more complicated.

it would need:

• add rotate parameter to SVGText
• "magic" calculation of SVG centre of rotation, so that the centre is identical in SVG output and PHP GD output
• change the 0 parameter of imagettftext angle in TextRenderer.php

any other glitches I've missed?

You're right, this is a much needed feature. But we need to make sure to not limit ourselves to text elements. E.g. #45 tracks rotation of rectangles and #30 tracks (among others) transforms in general.

the solution does not need to be perfect (no perfect solution was found in three years), we could start with simple text (as was in my PR ). other things (rectangles, ...) can follow later.

Please have a look at my PR. Since the addition of [Implement a Transform class #138] and [Implement transforms on nodes #148] another approach became possible.
