Why does windows explorer keep updating itself
Currently GIMP supports only gradient definitions from SVG images and its own gradients file format () that is far more complex than e.g. For example, it allows switching between various functions for blending between gradient segments which is desirable to achieve really complex and unique transitions between colors.
There's a nice selection of font managers on Windows and Mac, both commercial and free.
Adding support for Photoshop gradients () that has a limit of 512×512px size, as well as PNG, JPEG, TIFF among other file formats that are supported by gdk-pixbuf (a GTK own image library).
Contrary to GIMP's for gdk-pixbuf supported file formats the limit doesn't exist.
Whereas scripts are written in so called interpreted languages and thus run on any major platform as-is, most GIMP are written in C and thus have to be compiled for every target operation system. While Python is an interpreted scripting language, Python scripts are actually considered by GIMP as plug-ins and thus should be installed to same location where compiled plug-ins are.
Currently Pythons scripts do not have preview either, but this is bound to change.
