The qcam log prints one message per frame, which is pretty verbose. This
feature is useful for debugging, but not necessarily as a default
option. Silence it by default, and add a -v/--verbose command line
parameter to make the log verbose.
While this could have been handled manually by checking a verbose flag
when printing the message, the feature is instead integrated with the Qt
log infrastructure to make it more flexible. Messages printed by
qDebug() are now silenced by default and controlled by the -v/--verbose
argument.

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.

When ViewFinderGL::setFormat() is called, the fragment shader is deleted
and recreated for the new format. This results in unnecessary shader
recompilation if only the size is changed and the pixel format remains
the same. Keep the existing shader in that case.
The null test for fragmentShader_ can be removed, as if the shader
program is linked, the fragment shader is guaranteed to exist.

project, the build system files deserve particular attention. While they
describe how the binaries are created, they are not themselves
transformed into any part of binary distributions of the software, and
thus don't influence the copyright on the binary packages. They are
however subject to copyright, and thus influence the distribution terms
of the source packages.
Most of the meson.build files would not meet the threshold of
originality criteria required for copyright protection. Some of the more
complex meson.build files may be eligible for copyright protection. To
avoid any ambiguity and uncertainty, state our intent to not assert
copyrights on the build system files by putting them in the public
