This patch removes the Texture node from the compositor, which was based
on the legacy Internal Textures system in Blender. The main motivation
for removing this node is as follows:
- Procedural texturing nodes that previously existed in shading and
geometry nodes are now supported in the compositor, which cover 95% of
what is previously possible using and even adds new possibilities like
Gabor, Bricks, and various improvements to existing texture types.
- The old texture system did not support GPU evaluation, so it was
always computed and cached on the CPU, which causes bad performance
especially for interactive use in the viewport compositor. While the
new nodes are fully GPU accelerated and do not require any caching.
- The Texture node didn't support Texture nodes, so it was not fully
supported and we so far had a warning about that.
- The general direction in Blender is to remove the old texture system,
and the compositor was one of the last main users of it. 5.0 is thus
the ideal time to remove such use.
- The Texture node was always and still is a source of bugs, since it
relies on proper tagging for cache invalidation and updates, which is
so far not perfect. It also suffers from UI/UX issues, since it needs
to be adjusted from the properties panel, which can break if there are
other texture nodes in the context.
This is a breaking change and no versioning was attempted since:
1. It is impossible to get the same results as before due to the use of
different random number generators, so any versioning would just give us
the general look.
2. The Texture node supports a lot of possible configurations. For
instance, each general texture can have many options for the basis type,
and each basis type might have multiple options. So versioning all of
that will take a lot of time, code, and effort.

This patch adds a new Image Coordinates node for the compositor. The
Texture Coordinates and Pixel Coordinates outputs were removed from the
Image Info node and were added to the new node instead. Additionally, a
new Normalized Coordinates output was added.
The Pixel Coordinates output now no longer includes half pixel offsets.

This patch adds a new Image Info node which returns information about
compositor images. The node has three sources:
The node returns the following information:
- Pixel Coordinates: The coordinates of the centers of the pixels in the
image. Those are essentially the integer coordinates with half pixels
offsets added.
- Texture Coordinates: Zero centered pixel coordinates normalized along
the greater dimension. Somewhat analogous to Object coordinates in
shader nodes.
- Resolution: The resolution of the image.
- Location: The location of the image in the virtual compositing space.
- Rotation: The rotation of the image in the virtual compositing space.
- Scale: The scale of the image in the virtual compositing space.
This node is very useful to allow greater flexibility and procedural
creations. For instance, coordinates can be used to create procedural
effects like vignette using very simple math nodes. And size can be used
to compute size-relative parameters for pixel-parameter nodes.

By now it is just a "compositor", so move the files one folder up.
Things that were under realtime_compositor/intern move into
already existing intern folder.
