Define Span types explicitly as either variable- or fixed-sized. This
introduces a new convention for defining Span dimensions in the property
and control value definitions and generates Span types as variable-sized
Span<T> or as fixed-sized Span<T,N>.

The OpenGL ES shading language has no default precision declared
implicitly for floats in fragment shaders. The lack of an explicit
default precision results in shader compilation errors.
Specify a default precision of mediump for floats. This matches the
other fragment shaders, and is guaranteed by the OpenGL ES shader
language specification to be supported by all devices, while the higher
precision highp is optional.

Now that the ControlList::get() function returns an instance of

Previously, ControlList::get<T>() would use default constructed objects to
indicate that a ControlList does not have the requested Control. This has
several disadvantages: 1) It requires types to be default constructible,
2) it does not differentiate between a default constructed object and an
object that happens to have the same state as a default constructed object.
std::optional<T> additionally stores the information if the object is valid
or not, and therefore is more expressive than a default constructed object.

Support the X variants of the RGB pixel formats alongside the
equivalent Alpha component based versions.
The QImage::Format_RGB32 and QImage::Format_RGBX8888 formats only
specify that the alpha component must be 0xff. While the Qt
documentation doesn't guarantee that the alpha value will be ignored by
consumers, this seems to be the implemented behaviour, at least when
rendering with QPainter::drawImage().
The existing use of QImage::Format_RGBA8888 is updated to use the
QImage::Format_RGBX8888 variant to ensure that the image data is
visible.

When disconnecting a signal from a receiver, it is usually not necessary
to specify the receiver's slot function explicitly, as the signal is
often connected to a single slot for a given receiver. We can thus use a
simpler version of Signal::disconnect() that takes a pointer to the
receiver object only. This reduces code size, as the disconnect()
function is a template function.

Add support for 24-bit and 32-bit RGB formats. The fragment samples the
texture and reorders the components, using a pattern set through the
RGB_PATTERN macro. The pattern stores the shader vec4 element indices
(named {r, g, b, a} by convention, for elements 0 to 3) to be extracted
from the texture samples, when interpreted by OpenGL as RGBA.
Note that, as textures are created with GL_UNSIGNED_BYTE, the RGBA
order corresponds to bytes in memory, while the libcamera formats are
named based on the components order in a 32-bit word stored in memory in
little endian format.
An alternative to manual reordering in the shader would be to set the
texture swizzling mask. This is however not available in OpenGL ES
before version 3.0, which we don't mandate at the moment.
Only the BGR888 and RGB888 formats have been tested, with the vimc
pipeline handler.
