Render a single Primitive.

Params:

• primitive - The Primitive that is to be rendered to the screen.
• context - The piston2d-graphics drawing context.
• graphics - The piston Graphics backend.
• text_texture_cache - Some texture type T upon which we can cache text glyphs.
• glyph_cache - The RustType Cache used to cache glyphs in our text_texture_cache.
• image_map - Mappings from image widget indices to their associated image data.
• glyph_rectangles - A re-usable buffer for collecting positioning rectangles for glyphs.
• cache_queue_glyphs - A function for caching glyphs within the given texture cache.
• texture_from_image - A function that borrows a drawable texture T from an Img. In many cases, Img may be the same type as T, however we provide this to allow for flexibility.
