You have to use lower-quality fallbacks for interpolating between a "random" bunch of points and a rectangular grid of points using plgriddata, see src/plgridd.c. The only standard example affected by this is example 21 since it is the only one that uses the plgriddata command. However, even then the fallbacks are acceptable. For the record, dropping the direct dependency on freetype is potentially more serious since that means you are stuck with the Hershey font fallback for many device drivers. Those fonts give OK-looking results on printers, but those fonts are unhinted and therefore they give bad-looking results on displays. This issue does not affect cairo devices directly since they do not rely on the plplot core library for font handling. Instead, they rely on the cairo stack of libraries to handle fonts. That stack does include freetype (and a whole lot more) so in practical terms once you have the cairo device driver working for a cross build, then you should be able to add the cross-build freetype dependence to the plplot core library without any issues.
