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.

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

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).
