The opaque region of a weston view is updated only if the alpha value is 1 and the transform matrix is of type WESTON_MATRIX_TRANSFORM_TRANSLATE. While using ivi-shell, opaque region is never updated, as we are performing scaling operations to the view transform matrix, even when the scaling factor is 1 and thereby changing the type to WESTON_MATRIX_TRANSFORM_SCALE. Perform scaling of the view transformation matrix only when the scaling factor is non-zero. Signed-off-by: Rajendraprasad K J <KarammelJayakumar.Rajendraprasad@in.bosch.com>
