269ea7c489 internal/graphicsdriver/opengl: Refactoring: Reorder functions 
glPixelStorei affects the result of glTexImage2D. This change makes

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.

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.

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.

This is a preparation for iOS Metal, that runs drawing functions on
