cbb0a1da95 graphicsdriver: Refactoring 
This improved FPS on mobiles a little bit. Maybe now texture2D is
called only when necessary, but not sure.

742bbb4ccd graphicsdriver: Simplify clamping color values 
For negative values, OpenGL (and Metal) should take care of them
so we don't have to care.

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.

fd250c8d8c graphics: Rename NextPowerOf2Int -> InternalImageSize and add image size adjustment 
There is a minimum internal image size on some system like old iOS
devices. This change adds adjustment of the size.

ba47a19b17 mobile: Bug fix: error must be received without waiting for renderCh 
Even when error happens, the error was not received when renderCh
received. This was the cause of freezing when error happens.

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).
