Remove unnecessary transformations

Remove unnecessary transformations?

@tomkralidis I totally agree. Many of them were hidden side-effects of Inkscape's approach and flexibility. At the same time, the original intent was to simplify the coordinate values to be rounded to integers, to make display in pixel orientated systems simple too.

@tomkralidis It might be helpful to identify the different types of transforms that have been invoked. E.g.

1. A simple copy of existing WMO symbol part. This could be done using <defs>, <g> Groups, <path>, <symbol> or <svg> nested SVGs. The full list of container objects is ‘a’, ‘defs’, ‘glyph’, ‘g’, ‘marker’, ‘mask’, ‘missing-glyph’, ‘pattern’, ‘svg’, ‘switch’ and ‘symbol’.;
2. A simple translation of a WMO symbol part to another position within the symbol, such as multiple snow signs to make "moderate continuous snow";
3. A simple magnification/reduction of a WMO symbol part, such as to add hail to a thunderstorm sign;
4. A simple rotation of a WMO symbol part, such as for light intermittent rain and moderate continuous rain.

The original intent was to have a simple group of graphical elements in one consistent (integer) coordinate system, without any transforms, so that if someone wanted to plot them by hand on graph paper, they would achieve an acceptable result.
