moved over to the enum method of drawing. Not flexible, but type safe

+====== CanvasFrame ======
+
+[[/doc/sfml_rust/canvas/canvas_frame/struct.CanvasFrame.html|Documentation]]
+
+===== Details =====
+
+Canvas frame is at it's core, an accumulator of meta data to draw to the screen. 
+
+At the moment it is split up into these groups:
+
+* Colored items like non-textured sprites are just a list of triangles, simple vertices.
+@todo
+* Textured are grouped by their texture handle. Currently implemented as a list of lists of vertices. I don't think the vertices need to be grouped by sprite as long as they are triangle lists with texture coords included in the definition
+* Images are just the same as Textured
+* Text is a simple Font->Glyph lookup. XY coords of the font and the ASCII code
+
+{{{code: lang="rust" linenumbers="True"
+colored_drawables: Vec<RuntimeVertexDef>
+textured_drawables: HashMap<Arc<CanvasTextureHandle>, Vec<Vec<RuntimeVertexDef>>>
+image_drawables: HashMap<Arc<CanvasImageHandle>, Vec<Vec<RuntimeVertexDef>>>
+text_drawables: HashMap<Arc<CanvasFontHandle>, Vec<GlyphInstance>>
+}}}
+
+
+===== Future =====
+
+I like this immediate interface for this simple style of UI and drawing.
+
+@todo finish this
+
+Now. The CanvasFrame is closely coupled with the Drawable trait, the object which allows CanvasFrame to ingest all drawable object on a single interface
+
+Drawable needs a few things:
+	Handle to the Texture or Image it is using
+	Vertices describing it
+		(vertices will be character data for text)
+	Instances?
+
+The handle is queiried and then turned into a descriptor set in the draw_commands.
+
+* What if I pass using function params? But then how do I store???
+
+==== Problem ====
+I need to store vectors of multiple unequal types in a vec
+
+vec<vec<T>>
+
+Why can't I pass in
