- Added Cairo-based window snapshot conversion (with unpremultiplication) for drag icons and updated drag rendering to use the new helper instead of drawable capture.

Browse Source 
- Updated GtkXText to track the draw window and use a pixmap-to-surface helper for Cairo contexts, avoiding drawable references in the struct and rendering flow.
- Added a Cairo helper for capturing window-backed surfaces and used it when blitting during scrolling, fixing the build break from the removed drawable helper.
