X-Git-Tag: archive/raspbian/3.24.39-1+rpi1~1^2~24

a11y atspi: Fix reporting table cell pos at index (0,0)

Table (cell) row and column indices both start at 0, so
an index of 0 is valid.

Adapt the check accordingly and check for non-negative
indices instead of positive ones.

(`gtk_cell_accessible_parent_get_cell_position` sets -1
in the fallback case, so that's still handled as it used
to be.)

This fixes reporting the position of the table cell at
index (0,0) via AT-SPI.
