Synthetically emboldened raster font has its letters spaced too close
The automatically generated bold version of the raster font I'm using, while adds more weight to it, does not change letter spacing from the normal version, so the letters end up too close together. There appears to be a "spacing" property in fontconfig. However, trying to alter it with a .conf file doesn't seem to do anything.
Here's the font I'm using and a .conf file I attempted to write: MSSansSerifRaster.otb 99-ms-sans-serif-bold.conf
