Prefer RGB formats first, because they use less memory; but fallback to
RGBA formats, as they are formats required by OpenGL.

this fixes `WARNING: Running the setup command as `meson [options]` instead of `meson setup [options]` is ambiguous and deprecated.` warning while setting up the project
With rounded corners, X11 native border and blur enabled, left and
bottom 2*border_width pixels were not blurred, since mask did not
include border_width, only content width and height.
Create mask image with dimensions that include border width.

If a pixel is perfectly representable as an 8-bit number, don't add
dither. Reduce artifacts where dither is unnecessary.

Add bayer ordered dithering when presenting to screen. Reduce banding
when using a strong blur. Also use 16-bit intermediary textures to
preserve precision in the rendering pipeline.

Users with an old EGL version won't be able to use the egl backend. OTOH
we shouldn't prevent them from running picom because of a feature they
won't even use.
Don't assume the existence of EGL 1.5 symbols.

destroy_win_finish doesn't call win_release_images to free the images,
so we need to add a release_mask call there.

The intermediate texture used for shadow from mask calculation did not
properly set the min/mag filter to linear, which is required by the blur
methods. Because they use texture interpolation to accelerate
the convolution calculation.

Laying the usage message out by hand is tedious, also error prone
because the option names are duplicated at 2 places and have to be
consistent.
Create a struct to hold the option names and help messages, and
do layout programmatically.
