Pass 4 floats directly into the raster interface for color

Some of these interfaces are autogenerated by gpu/command_buffer/raster_cmd_buffer_functions.txt which has no mechanism for includes and thus only uses GL primitives. To get around this I'm unrolling the color as 4 floats and passing in r, g, b and a directly to these functions.

oop_draw_rect_query.png needed to be rebaselined because #808080 is not exactly the same color as rgb(0.5, 0.5, 0.5)
