Handle transparency

The import does not handle transparency right now.
- Transparency should be handled as "white" by default
- Make it possible to change the "height" for the alpha channel

For now the implementation will be as follows:
- If the alpha value for a pixel is lower than 255 we use the alpha channel to calculate the height
- 254 means black and 0 means white (the more transparent the lower the resulting geometry)
