Pixman Rasterization Skill

Apply this skill whenever a task involves pixman concepts, even if the current wlframe codebase does not yet use that pixman feature set.

Primary Goal

Produce pixman integration code that is correct about pixel formats, data access windows, and buffer ownership:

• Format mapping stays consistent with the chosen external pixel format model and endianness.
• pixman_image_t lifetime follows the backing buffer lifetime.
• Buffer listeners are linked and unlinked exactly once.
• Software rendering code remains explicit about raw memory access.
• Pixman operations, regions, transforms, and clipping are treated as semantics-sensitive rendering logic, not mere helper calls.
