ImageGrid is a class that imitates image manipulation libraries like PIL. Key differences from BlockGrid are:

Only 2D indexing is supported
Indices are [column, row]
Grid units are Pixel objects, which have .x (column) and .y (row) attributes
Grid origin defaults to the lower-left corner, but can be set to the upper-left
