Jehan dc3e815ff0 app, libgimp*, pdb, plug-ins: rename various public API name s/float/double/. 
Several types functions were using the wording "float" historically to
mean double-precision, e.g. the float array type (which was in fact a
double array). Or the scanner function gimp_scanner_parse_float() was in
fact returning a double value. What if we wanted someday to actually add
float (usually this naming means in C the single-precision IEEE 754
floating point representation) support? How would we name this?

Now technically it's not entirely wrong (a double is still a floating
point). So I've been wondering if that is because maybe we never planned
to have float and double precision may be good enough for all usage in a
plug-in API (which doesn't have to be as generic so the higher precision
is enough)? But how can we be sure? Also we already had some functions
using the wording double (e.g. gimp_procedure_add_double_argument()), so
let's just go the safe route and use the accurate wording.

The additional change in PDB is internal, but there too, I was also
finding very confusing that we were naming double-precision float as
'float' type. So I took the opportunity to update this. It doesn't
change any signature.

In fact the whole commit doesn't change any type or code logic, only
naming, except for one bug fix in the middle which I encountered while
renaming: in gimp_scanner_parse_deprecated_color(), I discovered a
hidden bug in scanning (color-hsv*) values, which was mistakenly using a
double type for an array of float.

This simple plug-in does an automatic contrast stretch. For each

contrast range. For some images it may do just what you want; for

Autostretch in that it works in HSV space, and preserves hue.

Propagates dark values in an image based on each pixel's relative
darkness to a neighboring average. The idea behind this filter is to
give the look of a black felt pen drawing subsequently shaded with
color. This is achieved by darkening areas of the image which are
measured to be darker than a neighborhood average. In this way,
sufficiently large shifts in intensity are darkened to black. The rate
at which they are darkened to black is determined by the second
pct_black parameter. The mask_radius parameter controls the size of
the pixel neighborhood over which the average intensity is computed
and then compared to each pixel in the neighborhood to decide whether
or not to darken it to black. Large values for mask_radius result in
very thick black areas bordering the shaded regions of color and much
less detail for black areas everywhere including inside regions of
color. Small values result in more subtle pen strokes and detail
everywhere. Small values for the pct_black make the blend from the
color regions to the black border lines smoother and the lines
themselves thinner and less noticeable; larger values achieve the
opposite effect.

$help = <<'HELP';
Propagates dark values in an image based on each pixel's relative
darkness to a neighboring average. The idea behind this filter is to
give the look of a photocopied version of the image, with toner
transferred based on the relative darkness of a particular
region. This is achieved by darkening areas of the image which are
measured to be darker than a neighborhood average and setting other
pixels to white. In this way, sufficiently large shifts in intensity
are darkened to black. The rate at which they are darkened to black is
determined by the second pct_black parameter. The mask_radius
parameter controls the size of the pixel neighborhood over which the
average intensity is computed and then compared to each pixel in the
neighborhood to decide whether or not to darken it to black. Large
values for mask_radius result in very thick black areas bordering the
regions of white and much less detail for black areas everywhere
including inside regions of color. Small values result in less toner
overall and more detail everywhere. Small values for the pct_black
make the blend from the white regions to the black border lines
smoother and the toner regions themselves thinner and less noticeable;
larger values achieve the opposite effect.

$help = <<'HELP';
Gives an image a softglow effect by intensifying the highlights in the
image. This is done by screening a modified version of the drawable
with itself. The modified version is desaturated and then a sigmoidal
transfer function is applied to force the distribution of intensities
into very small and very large only. This desaturated version is then
blurred to give it a fuzzy 'vaseline-on-the-lens' effect. The glow
radius parameter controls the sharpness of the glow effect. The
brightness parameter controls the degree of intensification applied to
image highlights. The sharpness parameter controls how defined or
alternatively, diffuse, the glow effect should be.
