Detailed Description

Owns the temporary storage used by glyph cache entry. The data pointers and size or cursor fields describe the live portion of the allocation; callers must use the type's cleanup path when the buffer or queue is no longer needed.

The useful part of rendered cell is in character, foreground, background, pixels: together they describe what is pending, who owns it, and how much data is valid. Keep the object with its parent operation and use the parent cleanup path.

This is the handoff point for terminal renderer. Callers fill vt, vts, cols, rows before passing it on; consumers read the values during the operation and return ownership only where the member contract explicitly says they do. Cached glyph bitmap with metadata. Stores pre-rendered FreeType bitmap to avoid rasterization on every frame.
