Theme development - line width in "dp"
I am attempting to update my themes to make them compatible with devices of differing dpi, using "dp" to define sizes.
It seems that there is a minimum line widths that can be rendered this way of 0.25dp. Lines narrower than this render as it they were 0.25dp, which is quite wide at higher zooms. This is the case both in lines and borders to areas. No such limitation appears to apply with standard numerical definitions of widths. An example of this would be in contour lines:
<line stroke="#A07F5F" stroke-width="0.15"/>
<line stroke="#A07F5F" stroke-width="0.15dp"/>
Is this intentional?
