8ed09861dc present: Call driver check_flip after we finish with our checks

186e269a9d glamor/glamor_egl.c: Skip modifiers that do not result in images 
that can be rendered to

According to https://registry.khronos.org/EGL/extensions/EXT/EGL_EXT_image_dma_buf_import_modifiers.txt ,
there is an interface that allows us to detect if a given format modifier is supported.

For example, nvidia uses this to report that pitch-linear images can't be
rendered to.

Since we are only interested in formats that we can actually render to,
we should strip these formats from the modifier list.

2a41522349 os: make FormatInt64() handle LONG_MIN correctly 
When compiling with gcc 15.2.0 using -O3 -m64 on Solaris SPARC & x64,
we'd get a test failure of:

Assertion failed: strcmp(logmsg, expected) == 0,
 file ../test/signal-logging.c, line 339, function logging_format

because 'num *= -1' produced a value that was out of the range of the
int64_t it was being stored in.  (Compiling with -O2 worked fine with
the same compiler/configuration/platform though.)
