Added ubo class template for handling Uniform Buffer Objects. This class automatically finds the offset and alignment for given data in a GLSL std140 uniform block. This makes it easy to just assign data through the gfx::ubo interface and bind that to the relevant shader_program's uniform block Changed shader_program's method of handling uniforms to match more closely to how vao handles its attributes. That is to call with the location as argument to get a proxy object on which to operate. I find this nicer to work with than having everything to do with uniforms in the shader_program class itself Add a flat_camera class which just assigns the near and far plane to 0 and 1 respectively Start work on a gui system which i'm really not confident about. Attempting to rethink how renderers work, but also no really confident about where i'm going with it Break out vbo_scoped_map into a more general scoped_buffer_map class so that vbo and ubo can utilize it Remove old gl_buffers units that were not really being used since my change over to opengl DSA functions Change the gfx::resource_manager to keep shared_ptr's in the container so the data can be more nicely shared Add missing aliases in math::fwd_declare.hpp for boolean types Change orthographic projection generator function to have the z values behave more in line with how opengl handles z depth. May have to undo this at some point but it seems to behave correctly now Fix some rvalue related aspects of util::deferred '
