- HLSL changes: [MooglyGuy] * Upped vertex buffer size to 64k verts, fixes assert in starwars and alphaone, please include the printed error message in any subsequent encounterings of the assert. * Improved vector rendering (beam width 1.5 suggested) * Ducked raster bloom default to 0.225 to reduce washout
