From: Eric Anholt Date: Thu, 14 Jun 2012 23:55:56 +0000 (-0700) Subject: mesa: Move glBindBufferBase and glBindBufferRange() to bufferobj. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b82c47215689d1243d1aa810bff7f06d8288d686;p=mesa.git mesa: Move glBindBufferBase and glBindBufferRange() to bufferobj. The rest of the TFB implementation remains in transformfeedback.c, and this will be shared with UBOs. v2: Move the size/offset checks shared with UBOs to common code as well.
