X-Git-Tag: archive/raspbian/4.12.3+ds-1+rpi1~1^2^2^2~22^2~1^2~253^2~10
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=fde3d2cd50585ec2abef1313fbf4cd189c88a2a1;p=gtk4.git

testsuite: Add testcase for z clipping

the near and far clipping plane are at -10000 and 10000 respectively.
Test that the renderers respect that.
