8ff42f55a1 internal/graphicsdriver/opengl: Give up restorign on browsers 
Using restorable images is expensive as this sometimes requires to
load pixels from GPU. On browsers, just reloading the application
should be fine when the context lost happens.

Closes #1603

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.

b1d7a5f595 shaderir/glsl: Enable dFdx for WebGL 
With WebGL1, an extension is required for dFdx. On the other hand,
with WebGL2, GLSL ES 300 is required and the extension is forbidden.
This change fixes shaderir/glsl to switch the output depends on the
WebGL version.

This change also adds a new build tag 'ebitenwebgl1' forcing WebGL 1.

59431e1cad graphicsdriver/opengl: Leave comments why we don't use PBO on Android 
Unfotunately, PBO might slow Android applications expecially when
coming back from context lost. Ebiten sends a lot of draw calls to
replace pixels in such case.

Until we find a good solution, let's not use PBO on Android.

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.
