PETROG

Enhancements:

Class names (e.g. "Detrital Grains", "Bioclastic Grains") are now user-editable as these are now read from the first line of the relevant database table, as opposed to previously being fixed.  The updated class names are used consistently in reporting, graphics etc.

New options when plotting grain size histograms, extending the image formats available in the existing functionality for automatically generating plots for all samples.

Bug fixes:

Fixed various issues with grain size histograms, including:

- correct updating of the plots when cycling through samples in a project;

- fixes relating to Wentworth scale;

- the "Show Binned Values" button now outputs the correct data.

Fixes in Outline logging (advanced textural), including:

- grabbing of an image and subsequent digitisation of outlines now works at all camera zoom levels;

when closing the grabbed image window, any "in progress" digitisations will be automatically discarded and properly cleared so they do not cause errors when re-entering the window;

stretch factors are now only applied when working with grabbed images when stretch is active (fixing an issue for certain cameras).
