gsdx-ogl:
* implement shader code (subset that seem to be used in SW mode) * some hack to fix some alignment issue with GSVertexPT1 structure * Lots of various opengl fixes. Remaining unsupported GL feature are inside SDL. git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl@4974 96395faa-99c1-11dd-bbfe-3dabce05a288
