This patch fixes T90207, T81266 and T8126690901.
This patch reworks the polygon offset algorithm used in blender.
The solution is based on finding a minimum distance value (epsilon) that corresponds to the smallest change in the calculated final NDC depth valuto create a new `projmat_depth_offset` utility that edits the projection matrix based on the desired depth range.
With tThis epsilon, a new projection matrix is calculated soallows a much simpler and more precise control of the offset that the geometry is drawnis intended to be obtained with a new depth a little bit smallerprojection matrix.
