 Drawing parameters defines which GPU functions to use and at which state. For example, to render transparent
 objects you need to enable blending with specific blending rules. Or you need to disable culling to draw objects

+- `cull_face`:
+  - Defines which side of polygon should be culled.
+  - **Possible values:** `None`, `Some(CullFace::Back)`, `Some(CullFace::Front)`
+- `color_write`:
+  - Defines which components of color should be written to a render target
+  - **Possible values:** `ColorMask { .. }`
+- `depth_write`:
+  - Whether to modify depth buffer or not.
+  - **Possible values:** `true/false`
+- `stencil_test`:
+  - Whether to use stencil test or not.
+  - **Possible values:**
+    - `None`
+    - `Some(StencilFunc { .. })`
+- `depth_test`:
+  - Whether to perform depth test when drawing.
+  - **Possible values:** `true/false`
+- `blend`:
+  - Blending options.
+  - **Possible values:**
+    - `None`
+    - `Some(BlendFunc { .. } )`
