-Fix stride on vertex
-Created projects and solutions for x64
-Using one solution/project for both x86 and x64 builds
-Fix stride on pos4col4 vertex layout
-Build targets
-Default rasterizer is back
-Fixed winding on segment/roundrect
-Fixed winding on grid
-Render context has flag to indicate if compute/buffers are supported
-Buffers remove raw floag if not supported
-Small fix on primitives to use context instead of device
-Fix winding on torus
-Fix winding on octahedron
-Fix buffer length on tetrahedron (vertex buffer broken)
