Adding GPU object:
Handles Vertex and Normal drawings as they are different between ES and desktop version.
In future, it should handle color, textures, maybe effects.


How it does it:
Desktop version:
* Calls usual gl functions for doing these things. For example glVertexPointer
ES version:
* Gets location of corresponding attributes at shader creation.
* Also stores matrixes' locations
* Before drawing, we select corresponding storage to the shader/object
* When we call functions, we set attribute to given pointer at recorded location
