Function isSkipDrawing

isSkipDrawing(material: Material, primitive: Primitive): boolean
Determines whether drawing should be skipped for a given material and primitive combination.

This function checks if the material has a valid shader program for the specified primitive. If no valid shader program is available (indicated by a UID of -1), drawing should be skipped to avoid rendering errors.
Parameters
- material: Material
  The material to check for shader program availability
- primitive: Primitive
  The primitive that will be rendered with the material
Returns boolean
true if drawing should be skipped (no valid shader program), false otherwise
Example
```
const shouldSkip = isSkipDrawing(myMaterial, myPrimitive);
if (!shouldSkip) {
  // Proceed with rendering
  renderPrimitive(myPrimitive, myMaterial);
}
```
