2a8e8d0eb6 internal/graphicsdriver/opengl: Stop using PBO
PBO was introduced to improve the performance at ReplacePixels,
but we found that PBO can degrades the performance. Also, now
multiple glTexImage2Ds are called successively like a batch, so
the situation is now different from that time when PBO was
introduced.

Let's remove PBO usages and wait and see.

Closes #1678

6b3c51921c internal/driver: Remove Image.Sync
Syncing is no longer needed for Metal, and additionally, OpenGL's sync
implementation was mock.

ed494dbf59 restorable: Reland: Do not record pixels if restoring is not requried
This change also remove the restrictions of operations on
graphicscommand.Image. For example, now DrawTriangles and
ReplacePixels can be mixed on the same image.

Fixes #1022

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.

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.
