bef54a382d transform: Improve docs 
Add an example for reconstructing transforms.

6a60214e8c gsk: Handle 2D transforms better 
For 2D transforms, we can read the scale
factors more directly off the matrix.

This should eventually be moved out into a
function to decompose a 2D transform into
scale + rotation + skew + translation.

27d662f1aa node editor: Preserve aspect ratio 
We don't want to distort our rendering.
Tell the paintable to keep the aspect
ratio.

52a8492887 rendernodepaintable: Provide accurate aspect ratio 
Since we report width and height as integers, the
default implementation of this introduces rounding
errors. This shows up in the node-editor, as having
uneven scale factors like sx=1.0 and sy=1.0035.
Text nodes don't handle uneven scales like that well
and overdraw.

37a7c6780a icontheme: Implement gtk_icon_theme_lookup_by_gicon() for textures 
More feature parity.

Before this, it would have worked just as well - just going via a PNG
bytes step inbetween.

1b85b5597b texture: Implement GIcon and GLoadableIcon 
This is mainly for feature parity with GdkPixbuf. And it doesn't hurt
anyone (I hope).

fae32846c7 texture: Refactor gdk_texture_new_from_bytes() 
1. Split into a real loader and a fake one

2. Only try the fake one if the real one doesn't support the file.

b271a94f92 texture: Rework error enum 
1. Change INSUFFICIENT_MEMORY to TOO_LARGE
   GTK crashes on insufficient memory, we don't emit GErrors.

2. Split UNSUPPORTED into UNSUPPORTED_CONTENT and UNSUPPORTED_FORMAT
   So we know if you need to find an RPM with a loader or curse and
   the weird file.

3. Translate error messages, they are meant for end users.

b5da07f0e1 icontheme: Use textures more 
We were going via GLoadablieIcon/GInputStream for everything previously
and we have no API for that with GdkTexture.

With this commit, gdk-pixbuf isn't used anymore when starting
widget-factory for anything but SVG.

a85f4ec6c2 icontheme: Load textures directly when possible 
This doesn't fix the codepaths for SVG (both for recoloring and
resizing) and doesn't handle streams yet.

b226478e8b Support 16bit formats in the png loader 
When loading, convert all >8-bit data to
GDK_MEMORY_R16G16B16A16_PREMULTIPLIED.

When saving, save all 8-bit formats as 8-bit RGBA,
and save all >8-bt formats as 16-bit RGBA.

2d3de8608c texture: Split out type detection 
This way, the code using it becomes clearer and we can use it in
multiple places without accidentally doing it wrong (hint: see next
commit).

d27bc74481 Use our own loaders for content (de)serialization 
Use our own loader to (de)serialiaze textures
to and from png and tiff.

We still fall back to gdk-pixbuf for handling all
the other image formats, and for pixbufs.

729ba8111a Add code to load jpegs 
This lets us avoid gdk-pixbuf for loading
textures from the common image formats.

As a consequence, we are now linking against libjpeg.

d30a029689 Add gdk_texture_save_to_tiff 
This is a companion to gdk_texture_save_to_png, using
the tiff format, which will let us avoid lossy conversion
of HDR data, since we can store floating point data.

the future.

a03594df52 Add code to load and save tiff files 
Add support for the tiff format, which is flexible
enough to handle all our memory texture formats
without loss.

As a consequence, we are now linking against libtiff.

d7c8f92733 Add gdk_texture_save_to_png_bytes 
Just expose what we already have available
internally, so e.g. tests can use it without
static linking.

f51f7f85eb Add code to load and save pngs 
Using libpng instead of the lowest-common-denominator
gdk-pixbuf loader. This will allow us to load >8bit data,
and apply gamma and color correction in the future.
For now, this still just provides RGBA8 data.

As a consequence, we are now linking against libpng.
