Attempts to move the Active Position upwards to a lesser numbered row, or leftwards within the same row to a lesser numbered column, are now highlighted red within the triplet list so the user can see which triplets are being ignored due to these errors. Detection for other triplet errors such as reserved bits/values or object related errors will be added later on. This is a part of moving the Active Position logic from the renderer to the triplet list, so a renderer won't be needed if the ability to editing (G)POP pages is added in the future.
