This stitches alignments into a single continuous display in reference coordinates, filtering to only selected species and removing insertion columns where the reference has gaps. Key changes: - mafClick.c: rewrite mafOrAxtClick2 to build species orderList from trackDb settings (speciesOrder, speciesGroup, speciesUseFile) respecting speciesDefaultOff and cart on/off state via cartUsualBooleanClosestToHome, matching the hgTracks species selection logic in newSpeciesItems(). Add mafStripRefGaps() to remove insertion columns from mafFrag output. Show spaces instead of dots for matching bases in diff mode. - hgMaf.h/hgMaf.c: add hgMafFragFromMafList() public wrapper for pre-loaded mafLists (AXT/custom mafFile support). Change hgMafFragHelper to skip species not in orderList instead of errAbort. Track per-species source coordinates (src, start, end, srcSize, strand) in struct oneOrg so browser/DNA links work correctly in mafFrag output.
