No functional changes. The code previously contained redundant and complex checks for different snapping scenarios, which involved combinations of multiple snapping flags and modes on each mouse interaction. This resulted in unnecessary code duplication and overhead. To address this issue, the code has been simplified and micro-optimized by moving these checks to the initialization of the snapping parameters. This results in a more streamlined and efficient codebase.
