Revert "Revert "Fix previous image references in OptimizeImageLayers (#983)" (#984)" (#993)

Commit 91fd0ac1dda4e0d1109ac70080f55b5286b6abc5 can be safely reverted
because commit b5a7073da902c79264ef8d3ccc8dd715fed8222d has same effects
in terms of intermediate image dimensions.

Assert image page dimension in OptimizeLayerFrames (#990)

OptimizeLayerFrames initializes the background with some assumptions for
image page dimension.

Do not refer to page in OptimizeLayerFrames (#987)

page dimension was used to create images to compare different disposal
methods. However, functions used for the comparisons, namely
CompareImagesBounds and IsBoundsCleared are based on the dimensions of
images themselves.

Creating image with page dimension is inefficient when converting images
with larger pages and therefore should be avoided.

Eliminate invalid montage directory exception
