Subject: mesa: fix inital value for new renderbuffer
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1f5bd65efa228736d41956f9e76df350dfe2d5d2;p=mesa.git

mesa: fix inital value for new renderbuffer

EXT_framebuffer_object bspec says:

    Get Value                          Type    Get Command 		Initial Value
    -------------------------------    ------  -----------      	-----------
    RENDERBUFFER_INTERNAL_FORMAT_EXT   Z+     GetRenderbufferParameterivEXT  RGBA

NOTE: this is a candidate for the 7.11 branch
