3df198f68e graphicsdriver/opengl: Use GL_READ_WRITE at glMapBuffer

65fdf48cbf graphicsdriver: Refactoring: ReplacePixels takes multiple arguments 
This reduces the number of graphics commands, and this works more
efficiently if the driver has an efficient way.

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.

09ca873c41 graphicsdriver/opengl: Use glBindAttribLocation instead of glGetAttribLocation

Instead of implicit indices of attribute variables, use explicit
