- idk why though, the algorithm isn't finding close, but nearby intersections

Bug Fix: dummy vertices are not intersections
* the function document_message_handler::sort_layers sorts the layers from bottom to top
- we want the reverse
* Bug Fix: ClosePath must be appended to shapes constructed from cycle
- By default PathGraph edges are not closed.
- When the input shape was not closed there would be multiple unclosed paths in the resulting shape, causing bugs
* close_path now closes all subpaths in a path
- if a shape has any subpath which is not closed boolean operations are undefined
(Also PathGraph::add_edges_from_path breaks when the path isn't closed)

* Created wasm binding to action's of the radio buttons which control the view mode
Added entry to DocumentMessage Enum
* draw in wireframe mode by changing parameters on each shape
added functions/changed behavior to do as above
not working yet
- newly added shapes should be drawn in wireframe
- setting fill to "none" on a path does not only draw an outline
- maybe the stroke width is 0?
* Wire frame view mostly functional for ellipses
- Need to implement for all shapes
- BUG: shapes don't immediatley update upon changing view-mode
* Fixed: active document now updates after view mode swap
* The Pros:
- wire frame mode effects all shapes correctly
The Cons:
- wire frame mode effects everything, including things that maybe shouldn't be, like select boxes and pen lines
* wire frame view no longer effects overlay layers
* Fixed: While in wireframe view the pen tool will draw regular thickness lines.
* some commenting
* Fixed potential bug:
In layer/file system with a Folder layer with a sub-layer that is also
a Folder cache_dirty must be set in order for all shapes to update properly
* refactored code to use ViewMode enum names throughout
* Changed: All wireframe lines are blank
cargo fmt
* Wireframe thickness doesn't change as a result of zooming
- Added DocumentMessage::ReRenderDocument, which marks layers as dirty and renders with the updated render-string
- All "zoom" messages in the movement_handler send a re-render message
- while in wireframe view, the "render-transform" of all shapes includes the root layer transform
Added getter/setter methods for graphene::Document::view_mode
* cargo fmt
* wireframe now has proper thickness after "Zoom Canvas to Fit all" action
* Refactored
- Changed FrontendMessage::UpdateCanvas to RenderDocument message to allow for lazy evaluation
- Created DocumentOperation::SetViewMode to be more consistent with existing code
- removed log statement
- Added constants for empty fill and thin-black stroke
* cargo fmt
* Removed ReRenderDocument message
