Subject: Add test to ensure that unused shaders are dropped from a trace.
X-Git-Url: https://git.cworth.org/git?p=apitrace-tests;a=commitdiff_plain;h=31ced6ae11a71b417589e21fd6bfc7805ead96c8

Add test to ensure that unused shaders are dropped from a trace.

This tests functionality which was added even more recently to
"apitrace trim".
