Bug Report: Annotation thickness is interpreted in device units rather than user space units
According to the PDF specification (v1.7), clause 12.5.2, the Border entry in an annotation dictionary (table 164) specifies the border width in user-space units. However, Adobe Acrobat Reader treats these as device-space units (i.e., pixels).
The attached PDF document defines borders with 1-unit and 5-unit widths; however, in Adobe Acrobat Reader these borders are always 1px or 5px wide, regardless of the zoom level.
