Add a "Pixel Density" sub-panel to render output settings which can be used to set the density (as pixels per inch for example). This is then written to images that support pixel density. Details: - The scene has two values a PPM factor and a and base unit. - The base unit defaults to pixels per inch as this is the most common unit used. - Unit presets for pixels per inch/centimeter/meter are included. - The pixel density is stored in the render result & EXR cache. - For non 1:1 aspect renders, the density increases on the axis which looks "stretched", so the PPM will print the correct aspect with non-square pixels.
