Description
Some problems I came across while testing for JuliaImages/ImageFiltering.jl#160:
- border "reflect" seems to fail for non-symmetric windows
mapwindow(minimum, 1:8, -2:0; border="reflect") # DimensionMismatch
- borders
NA()andNoPad()don't work
mapwindow(minimum, 1:8, 3; border=NA()) # MethodError
mapwindow(minimum, 1:8, 3; border=NoPad()) # MethodError
- fails when given
indicesentirely inside the border:
mapwindow(minimum, 1:8, -2:0; indices=1:2) # AssertionError on master, DimensionMismatch with JuliaImages/ImageFiltering.jl#160

Research direction
Start by reproducing the three mapwindow examples in the issue and tracing the mapwindow implementation. Done means non-symmetric reflect borders, NA()/NoPad() borders, and indices entirely inside the border are handled without DimensionMismatch, MethodError, or AssertionError.
