* The second opengl texture coordinate (gl_TexCoord[1]) are now filled in as well, and will give canvas coordinates from 0.0 to 1.0. The first texture coordinates still give the coordinates in the texture that is being used, which may not match the canvas exactly, so both coordinates are needed. * Also optimization to allow using smaller texture sizes with multiple smaller viewports. * Print the detailed GLSL shader errors (once), for easier debugging.
