A content snap providing the mesa userspace libraries and drivers for core20
This supplies the graphics-core20 content interface:
.../lib contains the mesa shared libraries (add to LD_LIBRARY_PATH)
.../dri contains the mesa drivers (set LIBGL_DRIVERS_PATH/LIBVA_DRIVERS_PATH to this)
.../glvnd/egl_vendor.d contains the mesa ICD (set __EGL_VENDOR_LIBRARY_DIRS to this)
.../etc/mir-quirks contains any Mir configuration for driver support (none for mesa)
.../libdrm contains mesa configuration for driver support (layout to /usr/share/libdrm)
.../drirc.d contains mesa app-specific workarounds (layout to /usr/share/drirc.d)
