generally speaking, if I'm tracing an app, I want to see what's happening to
my driver, not what's happening to tc, as tc does rewriting of command streams
which can affect the operation of the driver
use GALLIUM_TRACE_TC for previous behavior

similar to amd/radv driver debug modes for sqtt, this specifies a filename
which is checked on every flush(PIPE_FLUSH_END_OF_FRAME); when it exists,
the next frame (and only that frame) is captured into the trace
to use, specify a file with the env var, run your app, and 'touch /path/to/file'
when you want to capture a trace
