[Gimp-developer] Precision Conversion Dithering and Triangular wave gradient issues

[Elle Stone <ellestone ninedegreesbelow com>]

Precision Conversion Dithering and Triangular wave gradient both fail:

1. The Precision Conversion Dithering doesn't seem to work at 32- and 
64-bit precision, at least not on my computer (lower precisions work). 
If I say "yes, dither", one CPU runs at 100% forever, even with a very 
small image, accomplishing nothing at all. The only way to make it stop 
is to kill the GIMP process from the command line. The terminal output 
looks like this:

(gimp-2.9:2479): GLib-GObject-WARNING **: value "32" of type 'gint' is 
invalid or out of range for property 'red-bits' of type 'gint'

(gimp-2.9:2479): GLib-GObject-WARNING **: value "32" of type 'gint' is 
invalid or out of range for property 'green-bits' of type 'gint'

(gimp-2.9:2479): GLib-GObject-WARNING **: value "32" of type 'gint' is 
invalid or out of range for property 'blue-bits' of type 'gint'

(gimp-2.9:2479): GLib-GObject-WARNING **: value "32" of type 'gint' is 
invalid or out of range for property 'alpha-bits' of type 'gint'


2. The "Triangular wave" gradient repeat sometimes (not always) causes a 
segmentaton fault, perhaps related to trying to adjust an already drawn 
gradient before committing the gradient and also when drawing a second, 
new gradient after the first gradient is drawn:
