New Render queues (#161)
* Add new render queues proof of concept + scissoring support (WIP) * Graphics: Adapt basic sprites rendering to new render queue system * Graphics: Fix layers when rendering sprites * Graphics/RenderQueue: Fix sprite default overlay * Graphics: Enable scissor test by default * SDK/Widgets: Enable scissoring on widgets * Graphics: Handle almost everything with the new renderqueues system Todo: - Billboard rendering - Proper model rendering * Graphics/RenderQueue: Billboard drawing now works (WIP) At 1/4 of previous code performances due to individually process of billboards * Add new render queues proof of concept + scissoring support (WIP) * Graphics: Adapt basic sprites rendering to new render queue system * Graphics: Fix layers when rendering sprites * Graphics/RenderQueue: Fix sprite default overlay * Graphics: Enable scissor test by default * SDK/Widgets: Enable scissoring on widgets * Graphics: Handle almost everything with the new renderqueues system Todo: - Billboard rendering - Proper model rendering * Graphics/RenderQueue: Billboard drawing now works (WIP) At 1/4 of previous code performances due to individually process of billboards * Graphics/RenderQueues: Add full support for billboards * Graphics/RenderQueue: Cleanup and improve billboard rendering * Graphics/RenderQueue: Fix model drawing * Examples/Particles: Fix lighting on space station * Graphics: Cleanup forward render queue/technique * Fix compilation under Linux * Graphics/ForwardRenderTechnique: Fix case when scissoring is enabled on material but disabled on element * Add support for Deferred Shading * SDK/Widgets: Fix widget rendering * Graphics: Remove legacy code from render queues * Graphics: Fix some objects sometimes not showing up due to broken scissor box * Fix compilation error * Sdk/GraphicsGraphics: Fix bounding volume * SDK/World: Fix self-assignation * Update changelog for render queues
