Fixed:
- `delete_rows()`/`delete_columns()` incorrect row heights/column widths after use
- Tab key not seeing cell if out of sight
- Row height / column width resizing with mouse incorrect by 1 pixel
- Row index not extending if too short when changing a specific index
- Selected rows/columns border fg not displaying in cell border
- Various minor text placements
- Edit index/header prematurely resizing height/width
Improved:
- Significant performance improvements in redrawing table, especially when simply selecting cells
- All themes
- Can now drag and drop columns and rows with or without shift being held down, mouse cursor changes to hand when over selected
Changed:
- Dropdown box colors now use popup menu colors
- Checkboxes no longer have X inside, instead simply a smaller more distinct rectangle to improve redrawing performance
