PDFBOX-4657: don't disable interpolation for downscaled stencils to avoid them becoming white or black
> Use smooth interpolation for stencils too
> -----------------------------------------

> Key: PDFBOX-4657
> URL: https://issues.apache.org/jira/browse/PDFBOX-4657
> Project: PDFBox
> Issue Type: Improvement
> Components: Rendering
> Affects Versions: 2.0.17
> Reporter: Tilman Hausherr
> Assignee: Tilman Hausherr
> Priority: Major
> Labels: interpolation, pattern
> Fix For: 2.0.18, 3.0.0 PDFBox

> This came up with the PDF in PDFBOX-4627... the pattern was invisible. This is because interpolation is currently disabled for all stencils. This invisibility problem is solved by using the rendering hints when a stencil is downscaled. Currently we don't, due to a past problem with the file survey.pdf (PDFBOX-1094). However this problem no longer occurs, likely due to other changes in the last 5 years.
