Improvements:
1. Tools > Compute Area... now allows the following 4 new options for a T3 2D Mesh area calculation:
   - https://www.opentelemac.org/index.php/kunena/blue-kenue/15071-set-start-and-end-value-according-to-timestep#46393
   1. when ALL 3 vertices are ABOVE the threshold
   2. when at least TWO vertices are ABOVE the threshold
   3. when at least ONE vertex is ABOVE the threshold
   4. when the average vertex value is ABOVE the threshold
2. Usability improvement for File > Open File Header...
   - Behaviour change 1: The currently selected object's file header will be shown (if there is one) BEFORE asking to browse for a file
   - Behaviour change 2: The title of the dialog box will now contain one of 2 context strings:
     1. Header for Selected Object's File:
     2. Header for File Browser's File:
3. The T3 2D Calculator will no longer pop up an Attribute Information Dialog box
   - Instead, the attribute type will be determined directly from the desired output
     type (i.e. 4 byte float or 8 byte float)
   - In other words, the Calculator dialog box has a check box "8 Byte Float" in the bottom right hand corner
     that will be used to determine the attribute type.
4. Some performance improvements related to loading T3 2D Scalars and Vectors and loading Selafin Scalars and Vectors

Bug fixes:
1. T3 2D Calculator fault
   - https://opentelemac.org/index.php/kunena/blue-kenue/15071-set-start-and-end-value-according-to-timestep#46284
2. 2D View display bug when showing a Selafin file AND a shift value is being used
   - The fault was that the computed min/max values kept historical min/max values (i.e. those before applying the shift)
   - i.e. CAttribute::IncrementAllValuesByDoubleAmount(double val)

Internal changes:
1. Incorrectly internally checking for an empty string when dealing with file spec objects
2. Moved drawing style code to a new class called ADrawingStyle; will help improve maintenance and reduce internal coupling
3. Attributes no longer have drawing styles; now only maintained on an object

EnSim Development Statistics:
- 14 code commits (273 changed paths) to CHyMS from 18 February 2025 to 7 March 2025 (3.12.30-beta)
- 430 unit tests pass (no change)
