Updates

• Fixed an issue causing touch scrolling to sometimes scroll the backlog infinitely
• Fixed manual linebreaks being removed from backlog text
• Fixed backlog entries being listed in literal order rather than historical order.
• Added vngen_log_get_index script to return historical log entry index from an entry’s on-screen order.
• Added new proportion scaling modes which scale relatively to changes in display scale
• Added new properties functions (vngen_get_*) to return the calculated width, height, x, y, xscale, yscale, and rotation of VNgen entities, factoring in animations and modifications
• Updated vngen_exists to optionally check a specific character for attachments, rather than check all characters
• Enhanced all built-in animations for use with perspective
• Reduced linebreak strictness so that text surface width can expand or shrink to fit text automatically
• Renamed vngen_pragma to sys_config for consistency with other new engine functions
• Standardized code to reduce redundancy and improve performance
