Question: In SVG Tiny 1.2 for PSS, which of the following transformations of embedded video content is NOT mandatory but can be optionally applied, considering increasing complexity order?
Option 1: Translation of the video element
Option 2: Rotation of video by any degree (e.g., 45°, 180°)
Option 3: Scaling of the video element
Option 4: Dynamic Transformation with arbitrary angles and dimensions
Explanation: According to SVG Tiny 1.2 specifications for PSS, while translation and scaling of the video element are mentioned as part of optional transformations in increasing complexity order, rotation is only permitted by 90°/-90° degrees, not by 'any degree' as suggested in Option 2. Dynamic Transformation with arbitrary angles and dimensions is discouraged due to its negative impact on frame rate and complexity for mobile devices. Thus, the correct answer, which is NOT a specified mandatory or optional transformation in the given context, especially highlighting the specificity of rotation degrees, is Option 2.
