Question: In the context of optimizing data representation for simple vector graphics and animations in Wireless Messaging (e.g., SMS), which combination of techniques does NOT primarily aim at reducing the bit length for numerical values or coordinates?
Option 1: Bit Packing & Variable Resolution
Option 2: Local Envelope & Switchable Coordinate System
Option 3: Palettes & Default Values
Option 4: Non-linear Coordinate System & Animation Timing
Explanation: Palettes reduce the number of bits needed by mapping colors and element IDs to predefined values, a technique more suited for categorical data (colors, IDs) rather than numerical values or coordinates. Default Values omit unnecessary data by assuming defaults (e.g., mono drawing when no color scheme is defined), not directly relating to optimizing bit length for specific numerical values or coordinate representations. In contrast, the other options involve techniques for reducing the bit length of numerical values or optimizing coordinate systems.
