Description
The TinyGL stipple pattern emulation was switched from using glPolygonOffset to use textures to avoid numerical issues (triangles were too close for software engine when drawing stipple in two passes). However, it doesn't work properly yet. While in some cases like the Driller DOS demo, it looks ok (but not entirely correct), some other stipple patterns like the ones in the Dark Side ZX demo (https://downloads.scummvm.org/frs/demos/freescape/darkside-zx-demo.zip) are completely broken. I have attached the different screenshots using OpenGL and TinyGL.
