Closes #112

This pull request introduces support for non-linear axis transforms (such as logarithmic and symmetric log scales), enhanced axis panning and zooming logic, and better numerical stability. The changes ensure that user interactions (panning, zooming) and axis fitting behave correctly for both linear and non-linear axes, and add new API methods for configuring axis transforms.

Axis Transform Support and API

• Added new functions (SetupAxisScale) to configure axis transforms (logarithmic, symmetric log, or custom) for each axis, updating internal transform and locator functions accordingly.
• Axis constraints and zoom limits now use double precision for improved accuracy and consistency with axis transforms.

Panning and Zooming Logic

• Refactored panning and zooming logic in HandleInput to use transformed reference points in NDC/pixel space, ensuring correct behavior for non-linear axes and proper handling of axis inversion.
• Plane/axis translation now computes new ranges by projecting reference points with mouse deltas, supporting non-linear scales robustly.

Axis Tick Generation

• Implemented new locator and tick generation functions for logarithmic and symmetric log axes, including automatic exponent step sizing and minor tick placement.

Numerical Stability and Precision

• Improved numerical precision in coordinate conversions and axis fitting, using double values throughout and updating transform caches after fitting.
• Fixed type conversions in utility functions for greater accuracy.
