Turned the OpenGL and disable transparency options as static members.

- Now OpenGL and the transparency disabling are set at startup and
not read again for displaying graphics, preventing graphic errors
before startup.

- We also agreed long time ago that SDL specific functions
should have a SDL prefix. The header has been rearranged a bit
to do so.

- Also fixed a possible discrepancy in the hasAlphaChannel() function.
