- use abstract class render_thunk_list_dispatch for the callback
instead of template parameter render_thunks
- add class scoped_glyph_positions_offset for temporary shifting
of glyph positions
- remove render_offset_placements
This update is in Ref #2649. It provides an update to markers and their processing such that:
* All shared_ptrs are no longer required around markers
* Markers are now const
* Changes all agg_renderers to use a image_data_any variant (only image_data_rgba8 is implemented currently)
* Changes the marker and marker_cache to use image_data_any images
* Changes the symbolizers so that they must be aware of the source data type they are attempting to render and the render type that is expected to be rendered into.
* Moves many utilities into image_utils, that were previously in image_32.
The kicker is that this still isn't working perfectly yet, but I am commiting so I don't have tears in case everything is lost on my computer.
Ref #2633
- splits process functions into new cpp files to reduce peak compile memory usage
- drops cairo_renderer_base to match agg_renderer design
- only cairo_ptr is accepted so cairo_surface_ptr must be converted into a context first
- fixes -fvisibility=hidden
