52f6be2639 graphicsdriver/opengl: Fix suspicious GL function calls
Before this change, the pixel object buffer is unbound just after
getting a pointer by glMapBuffer. This seemed suspicious.

This change fixes to do all pixel manipulations once between
glMapBuffer and glUnmapBuffer without changing a bound buffer.

This might fix a wrong rendering on some machines, but I am not
sure.

acc933b7c3 graphicsdriver/opengl: Experimental PBO implementation
This change is an experimental implementation to use Pixel Buffer
Objects. This reduces calls of glTexSubImage2D.

This works only on desktops. Unfortunately WebGL does not have
this features. Mobiles can have PBO as of OpenGL ES 3.

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

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.
