* Use target_include_directories to specify include paths
* Specify project root (parent of rtgui and rtengine) as include path
* Replace relative includes with normal includes

Changes:
- Icons now use the native hidpi support from Gtk (through Icon Theme)
- Icons are now directly generated from scalable file (i.e. SVG file)
- Widget sizes are scaled based on DPI and scale factor
- Font size is scaled based on DPI and scale factor
Some of the RT parameters that are currently associated to Adjusters are very
hard to edit precisely by dragging the sliders, because small changes to the
default produce quite visible results. Prominent examples include black level,
WB tint, raw black and white points, and lens correction parameters
(distortion, CA, vignetting, perspective). The problem is made worse for those
settings in which not only small changes are significant, but also the
associated Adjusters have a very large range (again, think of black point and
WB tint). This is due to the fact that the current Adjusters have a linear
response. This commit adds an option to use a non-linear (specifically
logarithmic) response, which causes the sliders to move "slowly" around a
designated pivot point, and progressively faster the further you move away
from the pivot.
Besides adding the functionality to the Adjuster class, this changeset also
enables this behaviour for the following adjusters:
- exposure compensation
- black point
- lightness/contrast/saturation/chromaticity (both in exposure and in L*a*b*)
- WB tint
- channel mixer
- lens corrections (perspective, distortion, CA)
- rotation
- raw black and white points
- raw CA correction
- 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.
