Subject: gl: set default VBO size 256K
X-Git-Tag: submit/tizen/20151214.061957~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a9838c25d1d3e99e802b1fd5882ae74171e7df41;p=platform%2Fcore%2Fgraphics%2Fcairo.git

gl: set default VBO size 256K

Set default VBO size to be 256K, previous 1M is too big to be handled on
at least intel driver with GL context <= 3.0

Set both egl and evasgl vbo size to be 16K
