Render a single Primitive.
Params:
primitive- ThePrimitivethat is to be rendered to the screen.context- The piston2d-graphics drawing context.graphics- The pistonGraphicsbackend.text_texture_cache- Some texture typeTupon which we can cache text glyphs.glyph_cache- The RustTypeCacheused to cache glyphs in ourtext_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 textureTfrom anImg. In many cases,Imgmay be the same type asT, however we provide this to allow for flexibility.
