• Increased maximum allowable dimensions for saved output image to 7500×3750 pixels. (Note: Also increased maximum possible request for memory to allow for saving larger output images.)
• Refactored interrupted projections to use an Interruption enum.
• Re-designed popup color menus to offer more choices from a palette rather than a list.
• Added Gnomonic projection (#93).
• Added Gnomonic cubed sphere projection (#94).
