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.

Bug: #816

7ff99d3965 graphicsdriver/opengl: Remove glGetError calls
As glGetError doesn't tell where the error happens, this is not
useful.

Fixes #815

04dc1faa9c graphicsdriver/opengl: Call glFinish before glReadPixels
It looks like glFlush is not enough at least on Travis CI.

Fixes #814

c6dd0a75d9 graphicscommand: Optimize replace-image calls
Now ReplacePixels command is called only when necessary.

This also ensures that DrawImage must be called after ReplacePixels
is called since there is a potential problem that rendering images
on a texture without initializing by replacing pixels might cause
problems (escpecially on Metal. Perhaps #593 might be related).
