When using this compute shader, the following validation errors appear.
This patch fixes the issue.
BUFFER_WR(cBuffer, uint, 1);
NUM_THREADS(1u, 1u, 1u)
void main()
{
cBuffer[0] = 0u;

The default provoking vertex on OpenGL is the last of a triangle, but
on D3D and Vulkan it is the first.
This patch sets the provoking vertex to the first vertex on OpenGL.
