- #138 are there existing routines which can be easily used in R for locating graphical elements?
- plan on GUI (elegance is impossible without GUI's); menus or floating panels
- brushing modes (none, and, or, xor, not, complement)
- transient vs persistent brushing

BCW's 1987 paper (dynamic graphics for data analysis)
- 3 paint modes: transient, lasting and undone
- undone is our brushing mode `not`
- 4 operations: highlight, shadow highlight, delete and label
- we do not have shadow yet
- label is our identify
- rotation
- scatter plot matrix
