Subject: vbo: Declare the index range invalid for DrawTransformFeedback
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a7011922f1d48357f18af4639fad008f6f33a984;p=mesa.git

vbo: Declare the index range invalid for DrawTransformFeedback

Right now, we're setting the range to [0, 0] which is obviously bogus.
Instead, we should set it to be invalid like we do for DrawIndirect.
