Devices such as trackpads will emit smooth scrolling (GDK_SMOOTH_SCROLL) events with
deltas smaller than +/-1.0 at high frequency.
Quantizing these to +/-1.0 leads to significant amplification of scroll speed to the point
of unusability
Scroll by delta instead of +/-1.0 in these cases, permitting smooth scrolling through panels that use this code
Some mice emit GDK_SMOOTH_SCROLL with deltas of +/-1.0 per detent. This patch will not change behavior
with such devices. However, if any mice emit deltas of smaller magnitude, the per-detent behavior will
change.
This turns `IdleRegister::add()` into a template function to make the
provided function pointers type safe. It also adds a `delete_data`
parameter to manage the provided data pointer even in `destroy()`.
...thanks to the new MyScrolledToolbar class (guiutils.h/cc). This is
valid for the FileBrowser tab (first and second line can be scrolled
individually) and the top and bottom bar of the Editor(s) tab.

- The "light" icon theme is now a little lighter, to increase contrast.
- Toolbox icons are now small.
- Buttons:
- Buttons without labels which use icons as their only source of info regarding what the button does (e.g. the white-balance pipette button) use normal-sized icons.
- Labeled buttons which use icons as an auxiliary source of information (e.g. Auto-Crop) now use small icons. Curve type icons are also small even though they have no labels.
- Colored circles are smaller.
- Curve type icons redesigned and small.
- Hand icons (when panning the preview) redesigned to have a clear outline regardless of background color.
- Magnifier icons redesigned to have a thinner magnifier frame and larger inner parts.
- Perspective, distortion and crop icons redesigned.
- Some small icons were missing the `-small` suffix, now renamed.
Do not try to show a native file dialog. I think this would be useless, since
RT already uses non-native dialogs in other places, and I'm not sure it would
be possible to replace all of them (e.g. in icmpanel.cc the dialog is
customized by adding a checkbox for WB, and this is not possible with a native
dialog).
