Detailed Description

Analyzes the expression to determine if 'x' or 'y' coordinates are used. Collects:

• A boolean indicating if 'x' is used.
• A boolean indicating if 'y' is used. This information is used by the IR generator to avoid generating unnecessary coordinate variables and calculations. Depends on: None
