refactor shapes to use configuration file and split into elements, lines and texts

does x, y, w, h need to be on lines (no for connectors, but other lines?)

update domain model with all the recent architecture changes

replace generated methods for shapes, texts and lines with meta programming

refactor HTML builder to custom GEM or use existing ruby GEM

add page background to theme, use it whenever the theme is set at a diagram/page level

move DrawioDsl::Formatters::Factory::FORMATTERS to resource file

move DrawioDsl::Formatters::StyleBuilder::MAPPINGS to resource file

settings style attributes need to de-duplicate, might be best to utilize the new StyleBuilder class

write SVG directly into other projects

Nodes need to support child nodes

Grid layout does not position itself in relation to the last element

Grid layout should not be affected by connector lines

Grid layout should support flow break (break to next section if less then boundary)

Grid layout should support hard break (break to next section)

Dynamic sized shapes that expand to the size of their text

Control of text padding left, right, top and bottom

Improve the theme control over text-only shapes

x,y settings do not work for shapes within a grid layout

page layout so that you drop elements on and they are positioned correctly, e.g centered, left, right, etc, maybe a grid layout with a wrap of 1 and a width of the page is sufficient
