Some nodes clamping HDR values

[僕の名前 (仮)]

Most of the nodes (especially atomic) support both HDR inputs and outputs, but some nodes are not fully support HDR.

I haven't looked at all nodes yet but the ones I looked:

Support both HDR input and output

Most of the nodes I checked support HDR, including:
pixel processor
fx-map
blend
uniform color
levels
distance
greyscale conversion
all blur types
normal
warp and directional warp
transform2d
text
cartesian/polar conversion
tri-planar projection
clamp

Don't support HDR

auto levels
ambient occlusion
bevel
tile generator
histogram scan
SVG
splatter, circular splatter
quantize
invert
curvature, curvature smooth, curvature sobel // hdr values are clipped, but you can convert heigthmap to normal map and make curvature from it.

Clamping input to 1.0 but can have HDR outputs

curve
gradient map
vector warp // clamps image to 1.0 but supports HDR vector map. Ironically, it needs to work the other way.

Work weird in 32b (use only in 8 or 16 bit)

Histogram range
Histogram scan (non-uniform)
Histogram shift
Gradient (dynamic)


I wish some of those nodes supported HDR. Curve is better than levels, but sometimes have to use levels because I have input with values outside of 0;1 range, or find work-arounds (designing graphs in a way so they don't have It would be useful to have HDR for various tile generators, too.

It would be cool for curve, if it was possible to double click on horizontal slider and add value more that 1.0, as you can do with vertical slider. You can do it for levels, why not for curve.
