Changeset 342

Timestamp:

Author:

Message:

• gl_context - set_draw_buffers accepts const
• gl_context - set_draw_buffers with 1 buffer behaves like set_draw_buffer
• camera - holds viewport info (does not set it, should it?)
• clear_state - NONE added
• device/uniform - nv_v_viewport & nv_v_screen_size built-ins added
