Subject: mesa: pass context parameter to gl_renderbuffer::Delete()
X-Git-Tag: android-x86-4.4-r1~2549
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=c73245882c7ff1277b190b97f093f7b423a22f10;p=android-x86%2Fexternal-mesa.git

mesa: pass context parameter to gl_renderbuffer::Delete()

We sometimes need a rendering context when deleting renderbuffers.
Pass it explicitly instead of trying to grab a current context
(which might be NULL).  The next patch will make use of this.

Note: this is a candidate for the stable branches.
