4021c24534 shader: Separate uniform variables and texture variabls
Textures cannot be treated as a regular variable, then they should
be treated differently from other uniform variables.

Add a new function texture0At replacing texture2D.

2a63512c6e driver: Add AddressUnsafe
This skips the source-region check and reduces 'if' branches from
shader programs.

AddressUnsafe is internal only so far. We might expose this value
later.

8fd377f1e3 driver: Add ImageID and use this
This is a preparation to introduce shaders. Shader programs
require images as uniform variables, but the current way would make
API complex unnecessarily.

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
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.
