Let's keep 'graphics' package as a package for utility functions
or testable functions as much as possible.

cbb0a1da95 graphicsdriver: Refactoring
This improved FPS on mobiles a little bit. Maybe now texture2D is
called only when necessary, but not sure.

742bbb4ccd graphicsdriver: Simplify clamping color values
For negative values, OpenGL (and Metal) should take care of them
so we don't have to care.

09ca873c41 graphicsdriver/opengl: Use glBindAttribLocation instead of glGetAttribLocation
Attribute variables are often optimized out and it is really hard
to prevent this.

Instead of implicit indices of attribute variables, use explicit
indices by glBindAttribLocation.

Bug: #816
