-"""DetailsViewer class.
-
-This class implements a pure input window which allows you to meticulously
-edit the current color. You have both mouse control of the color (via the
-buttons along the bottom row), and there are keyboard bindings for each of the
-increment/decrement buttons.
-
-The top three check buttons allow you to specify which of the three color
-variations are tied together when incrementing and decrementing. Red, green,
-and blue are self evident. By tying together red and green, you can modify
-the yellow level of the color. By tying together red and blue, you can modify
-the magenta level of the color. By tying together green and blue, you can
-modify the cyan level, and by tying all three together, you can modify the
-grey level.
-
-The behavior at the boundaries (0 and 255) are defined by the `At boundary'
-option menu:
-
- Stop
- When the increment or decrement would send any of the tied variations
- out of bounds, the entire delta is discarded.
-
- Wrap Around
- When the increment or decrement would send any of the tied variations
- out of bounds, the out of bounds variation is wrapped around to the
- other side. Thus if red were at 238 and 25 were added to it, red
- would have the value 7.
-
- Preserve Distance
- When the increment or decrement would send any of the tied variations
- out of bounds, all tied variations are wrapped as one, so as to
- preserve the distance between them. Thus if green and blue were tied,
- and green was at 238 while blue was at 223, and an increment of 25
- were applied, green would be at 15 and blue would be at 0.
-
- Squash
- When the increment or decrement would send any of the tied variations
- out of bounds, the out of bounds variation is set to the ceiling of
- 255 or floor of 0, as appropriate. In this way, all tied variations
- are squashed to one edge or the other.
-
-The following key bindings can be used as accelerators. Note that Pynche can
-fall behind if you hold the key down as a key repeat:
-
-Left arrow == -1
-Right arrow == +1
-
-Control + Left == -10
-Control + Right == 10
-
-Shift + Left == -25
-Shift + Right == +25
