I have updated the texture control files to correct a few errors. As well, I have added a new texture and enhanced another.
The new texture is
gp_TwyShoulder_100F. It includes four textures for drawing 3ft/1m wide taxiway shoulder lines - perpendicular at 50ft/15m and 100ft/30m spacing and 45 degree slanted lines at the same spacings.
I have also added an enhanced taxiway centerline to the
gp_PatternedLines_40F texture. This also allowed definition of a yellow 20' interval dashed line. The real-world enhanced centerline appears to repeat at 24' intervals. However, the texture sheet is defined as covering 100ft. So, unchanged, the new centerline texture will appear with a 20' repeat. If you want a true representation of the real world, you'll either have to slightly stretch the texture or, alternately, resize the line to appear a little shorter in the GP Editor.
Finally, the package contains both mipped and non-mipped versions of the textures. Choose whichever you wish.
If you are a new user, or your texture folders and texture control files contain only base entries, then you can simply copy (the contents of) the Textures_Dpy_Base folder and the selected Textures_Base folder into your ADE Textures_Dpy and Textures folders respectively and overwrite the two texture control files. If, however, you have added any of your own textures, you'll can probably still just copy the texture folders but you'll have to manually edit/recreate your texture control files.
I am unable to upload the new texture package as an attachment. (The error message just says "upload failed". Presumably there's a size limit on uploads.) So, instead, you can download it from my website
http://stuff4fs.com. Navigate to Applications / ADE_GP page and download the Base Textures.
