When Erasing or Painting, the Brush Scale value is limited from 0.01 to 10.00 along a logarithmic scaling widget.

For largish digital photos nowadays, with resolutions exceeding 3000 pixels per dimension, a "Circle Fuzzy (19)" brush with a multiplier scale of 10 will only result in a brush of size 190 pixels. 

This is not big enough especially if the user is trying to remove significant amount of the image area.

I have tracked down the modification file, and its located at

./app/paint/gimppaintoptions.c

on line 182 (of the 2.6.7 source) where the change

  GIMP_CONFIG_INSTALL_PROP_DOUBLE (object_class, PROP_BRUSH_SCALE,
                                   "brush-scale", NULL,
<                                  0.01, 10.0, DEFAULT_BRUSH_SCALE,
                                   GIMP_PARAM_STATIC_STRINGS);

to

  GIMP_CONFIG_INSTALL_PROP_DOUBLE (object_class, PROP_BRUSH_SCALE,
                                   "brush-scale", NULL,
>                                  0.01, 100.0, DEFAULT_BRUSH_SCALE,
                                   GIMP_PARAM_STATIC_STRINGS);


will increase the scaling factor from 10 to 100.
Because the UI is a logarithmic slider, the change should not affect the usability of the parameters much, but will provide the needed functionality of increasing the brushes to a respectable size.

I hope that we can include this change for all future changes of GIMP.

Thanks.

BTW, Im not sure why we would need Circle Fuzzy 07 - 19 now. It should just be Hard / Medium / Soft brushes - but this is a separate feature request.
