Matt Amos	b85e7d0764	Added method to extract bounding boxes for symbolizers. ... This is done by creating a fake 'virtual' environment at a fake point and running the symbolizer render code. The actual render is saved in a thunk for after the group layout has been done.	2014-02-18 11:11:06 -05:00
Matt Amos	ee018dc589	Factor common fields out of cairo renderer. ... This involved making the freetype engine stack allocated and accessible via a `shared_ptr` because `FT_Face` elements stored in it are referenced from cairo structures which persist beyond the lifetime of the `cairo_renderer` object. Hopefully this can be resolved in a future commit.	2013-12-05 18:39:09 +00:00
Matt Amos	a76e441174	Factored out common renderer fields. ... The idea here is that much of the code in the renderers and the various `process_*` rendering methods is shared, but this sharing is obfuscated by the lack of sharing of renderer fields and methods. This is the first step in trying to factor out commonalities in order to simplify the implementation of the renderers and make them easier to understand and modify.	2013-12-05 16:21:55 +00:00
