Added

* Added `BufferManager` to handle buffer data for all the scene objects.
* Added `make_texture_buffer` in `gl.py` for matrix and settings array.

Changed

* Greatly improved performance for scenes with large number of objects.
* All scene objects are rendered once in a combined buffer through single draw call.
* Updated shaders to version OpenGL 330 Core Profile.
* Implemented matrix and settings array as texture buffer instead of uniforms to improve performance.
* Blending of transparent objects is handled in a second draw on top of the opaque objects.

Removed

* Removed redundant Shaders: `grid_shader`, `instance_shader`, `surface_shader` and `arrow_shader`.
* Removed `paint_instance` from `Renderer` as it handled by a shader flag.
