* A {@link BufferedImage} with an 8x8-tile blit helper: takes a {@link TileDecoder}-shaped pixel grid |

|
* (values 0-3) and paints each pixel through a caller-supplied value-to-colour mapping - either one of |
|
9
|
|
* 4 evenly-spaced gray shades (before {@code NesPalette} existed, still used where no real palette |
|
10
|
|
* group applies) or 4 real {@code NesPalette} colours resolved from actual palette RAM. Optionally |
|
11
|
|
* flips the source horizontally/vertically (for OAM sprite attribute bits), can treat pixel value 0 as |
|
12
|
|
* transparent instead of painted (the NES sprite convention - lets whatever was drawn underneath show |
|
13
|
|
* through), and always clips against the image's own bounds - callers don't need to know/pass the |
|
14
|
|
* canvas size themselves. |
