ISSUE-2286: Resolving relative values in @kernelUnitLength (number-optional-number)

Resolving relative values in @kernelUnitLength (number-optional-number)

State:
RAISED
Product:
Module: Filters
Raised by:

Description:
When resolving relative values based on @primitiveUnits for @kernelUnitLength it's unclear what result is expected.

Example:
<filter primitiveUnits="objectBoundingBox">
<feConvolveMatrix kernelUnitLength="8" .../>
</filter>

a) @kernelUnitLength is expanded to "8 8", then relative values are calculated
b) relative values calculated for the x value, then duplicated to y

The kernelUnit will be slightly weird if the b) option is picked because it's then not depending on the height of the target element boundingbox at all. Thus I'm leaning towards clarifying that a) is the expected result.
