5ec67a8e90 backends/native: Change the MetaBezier API to sampling and lookup
This keeps the existing ClutterBezier implementation but changes
the visible API to match the needs of the tablet tool pressure curve:
a bezier defined within a [0.0/0.0, 1.0/1.0] box,(sampled
into a set of x->y mappings for each possible pressure input x, and
a lookup function to get those values out of the curve.

This patch moves the internally-only functions to be statics and changes
meta_bezier_init() to take only the second and third control point, as
normalized doubles. Because internally we still work with integers, the
bezier curve now has an integer "precision" that defines how many points
between 0.0 and 1.0 we can sample.

The meta_bezier_rasterize() function calculates the x->y mapping for
each point on the bezier curve given the initial scale of the curve.
That value is then available to the caller via meta_bezier_lookup().

The ClutterBezier code was removed in

because it wasn't used anywhere. We do need a bezier curve for the
tablet tool pressure curve calculation though so let's move it
to the native backend and rename it to MetaBezier in the process.

4f68713020 frames: Notify borders on first content resize
This addresses the following race condition:
1. Window+MetaFrame are created non-fullscreen, _MUTTER_FRAME_EXTENTS
   is initialized through widget measuring, accounting for frame.
2. Window and MetaFrame become fullscreen.
3. MetaFrameContent gets first size allocation, already fullscreen.
4. Borders were initialized to 0,0,0,0, become set to 0,0,0,0 correctly
   reflecting fullscreen, however notify::borders is not emitted.
5. _MUTTER_FRAME_EXTENTS stays accounting for the frame extents.

It sounds sensible to have the borders initialized to a meaningful value,
so account for the first time the border would be set due to the content
being (re)sized, and let this first value trigger notify::borders resulting
in _MUTTER_FRAME_EXTENTS updates.

Since all later _MUTTER_FRAME_EXTENTS changes happen through content
resizes, we only have to cater for this initial handover between the
frame/content initialization paths done through widget measuring and
the later paths done through MetaFrameContent resizes.

c8f4c85bfb wayland-buffer: Support MultiTexture formats via wayland shm
Finding the shm offset and shm stride for each plane is the main issue.
The rest is just creating multiple textures for each plane.

One assumption is that shm planes are always contiguous in memory so the
next plane comes directly after the size of the current plane.

The size of a plane is determined by the height and stride. There is
only a single stride parameter for shm buffers but we assume that the
first plane is always non-subsampled which gives us a number of "logical
elements" on one line (stride / bpp of the first plane). The stride of
the other planes is then the number of logical elements devided by the
subsampling factor and multiplied by the bpp of the plane.

5652c61c06 tests/wayland-test-clients: Use stride of the first plane
The assumption is that all planes are always contiguous, and we don't
have any multi-plane formats where the first plane is subsampled.

The stride of the entire buffer is then just the stride of the first
plane and the stride of the other planes is derived from that.

c0832b99d8 multi-texture-format: Always use the tex coords of the first plane
The texture coordinates of all planes should be the same in theory so
using the coordinates of the first plane works.

The reason for this change is that Cogl somehow doesn't manage to get us
the correct coordinates for the 3rd plane in some circumstances. This is
really a workaround but not wrong in any way.

33088d59db wayland/text-input: Pass char based offset to ClutterInputFocus

27bdf0c577 wayland/text-input: Use byte based offset in delete_surrounding_text
ClutterInputFocus/GtkIMContext uses char based offset for
delete_surrounding, however, text_input_v3 uses byte based offset for
it. Currently only GTK with mutter can work correctly via text_input_v3
because they both forget to convert between char based offset and byte
based offset.

This commit fixes it in mutter by saving committed surrounding text in
MetaWaylandTextInput and converting char based offset to byte based
offset with the UTF-8 encoded surrounding text.
