Try to look for switch(color) in plugins/blur/blur.C

and replace for testing 1.0 for rgba/rgb float cases with FLT_MAX ? Like in
our earlier work ....

case BC_RGBA_FLOAT:
                                BLUR(float, 1.0, 4);
                                                       break;

If it does not break plugin we probably can go for each noted plugin and
try to find where they clip ....
