Bugfix: Prevent genType from being inferred as int in GLSL wrappers

[reshma045]

Resolves #7900

Changes:

• GLSL genType Inference Fix:

  • Fixed an issue in ShaderGenerator.js where functions like sin() were incorrectly inferring genType as int when passed float literals (e.g., sin(0.5)).
  • Updated FunctionCallNode's determineFunctionSignature() to:
    • Coerce int to float when the expected argument type is genType.
    • Ensure only valid genTypes (float, vec2, vec3, vec4) are allowed.
    • Prevent invalid inference when only scalar literals are passed.
  • This resolves incorrect shader compilation and ensures that wrapper functions behave as expected.

• Unit Test Fix:

  • Modified a test in test/unit/io/loadTable.js to normalize line endings when asserting CSV content:

    const value = table.getRow(3).get(0).replace(/\r\n|\r/g, '\n');

    This ensures that the test passes on both Windows and Unix-based systems by handling \r\n vs \n newline inconsistencies.

Screenshots of the change:

A purple box rendered using sin(0.5) in the fragment shader confirms correct float type inference.
