Log Message:
Fix SGR pixel mouse coordinate origin
DECSET 1016 reports one-based pixel coordinates, but the conversion
from ciolib's zero-based high-resolution mouse position subtracted the one-based cterm origin directly. This removed one full character cell
from each axis and could report zero or negative coordinates near the
top or left edge.
Use the zero-based pixel origin implied by the one-based cterm cell
origin instead, and treat high-resolution coordinates as present only
when both axes are non-negative. This keeps valid zero-valued pixels
from being mistaken for missing data while preserving the text-coordinate fallback for backends that do not provide pixel positions.
Fixes SourceForge ticket 267.
