/**
|
|
* A class containing a set of flags indicating which parts of an
|
|
* <code>ImageryLayer</code> need to be processed.
|
|
*
|
|
* This is used in the <code>ImageryPipelineStage</code> to decide the
|
|
* structure of the function that blends the imagery texture information
|
|
* with the previous pixels.
|
|
*
|
|
* Each flag indicates that at least one of the <code>ImageryLayer</code> objects
|
|
* that are part of the input did <b>not</b> have the default value that
|
|
* was defined via the corresponding <code>ImageryLayer.DEFAULT_...</code>>.
|
|
*
|
|
* Note that the type of the flags can be <code>boolean</code> or
|
|
* <code>number</code>. Users should check for these flags having
|
|
* a 'truthy' or 'falsy' value.
