remap-tablet.sh [rels,abs,nos]

• nos real absolute mode (top left of screen is top left of tablet)
• abs fast absolute mode (top left of screen is about 1cm from center)
• rels slow relative mode (functions like a mouse where the entire tablet is equal to one screen)
• anything else fast relative mode (functions like a mouse with high sensitivity)
