Expand exports
Export imfilter_gaussian
Update for deletion of wait_success
Fix multidimensional overlays
Truncate trailing singleton dimensions in Overlay
Delete colorspace property from Overlay (it's RGB)
Be more flexible with 3d arrays

If the 3rd dimension is not 3, assume this is a 3d array with no colordim
Support colons in getindexim, subim, sliceim constructors
Add scale! (non-allocating)
Improve the type-specificity of Overlays
Major refactoring of uint32color

This appears to handle the nest of possible subarrays/overlays/other
weird array types better than previous efforts. It also yields fast
performance for arbitrary dimensions, thanks to Cartesian.
Clean up named->dimension conversion and support size(img, "x")

This also fixes what might have been an undetected bug,
incorrect indexing in images where color is an early dimension.
Add a sleep() to allow writing to finish before testing via read

I was getting ImageMagick library errors on some systems
Reduce loading time by selectively including Grid's Counter
Fix errors and omissions in color conversions
Add type declarations for faster generated code
Small fixes for overlays
Delete unused function parameters
Faster performance by forcing specialization on tuple inputs
Convert uint32color! to @nloops
