Subject: Expose '--notexturecache' command line argument to gm.
X-Git-Tag: accepted/tizen/5.0/unified/20181102.025319~16899
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e24a07980eee6a4a743b0099e2ed5d44bd9715c4;p=platform%2Fupstream%2FlibSkiaSharp.git

Expose '--notexturecache' command line argument to gm.

Pass '--notexturecache' to gm to resize the Ganesh texture cache to 0.  This stresses Ganesh's behaviour after a cache purge operation.
