glmemory: Fix handling of stride with alignement larger then 8
Setting a scaled factor for X coordinate is not enough as the indexer will still think stride is shorter and will not fully skip it. Instead, update width, so the lines are as expected. Combined with the scale, it will hide the cropped portion. https://bugzilla.gnome.org/show_bug.cgi?id=729896
