v2.14.1v2.14.1

- (Upgrade) EmguCV from 4.5.1 to 4.5.2
- **File formats:**
   - (Add) Getter `IsAntiAliasingEmulated`: Gets whatever a file format uses real or emulated AntiAliasing
   - (Add) Getter `IsDisplayPortrait`: Gets if the display is in portrait mode
   - (Add) Getter `IsDisplayLandscape`: Gets if the display is in landscape mode
- **Tool - Resize:** (#235)
   - (Fix) Division by 0 when start layer is equal to end layer
   - (Fix) Calculations when using the option "Increase or decrease towards 100%"
- (Add) About window: OpenCV build number and a button to copy build information to clipboard
- (Improvement) Exposure exposure finder: Improve the **Multiple brightness** section to auto fill with correct values for file formats that use time fractions to emulate AntiAliasing, this can be used to replace the **Multiple exposures** section
- (Fix) UVJ: Error when using a null or empty layer array on manifest `config.json` file (#232)
- (Fix) GCode parser: When only a G4/wait command is present on a layer it was setting the global exposure time and discard the this value per layer
