Rendering function optimization

The internal rendering function BiQ() at line 356972 was refactored to AiQ() at line 356971, removing unnecessary rows and columns parameters that were being passed through but not actively used by the core rendering logic. The function signature changed from accepting 4 parameters (A, B, Q, Z) to just 2 parameters (A, B), and the return value no longer includes rows and columns fields.

• Old: var BiQ = (A, B, Q, Z) => at line 356972 in v2.0.2
• New: var AiQ = (A, B) => at line 356971 in v2.0.3
