Gaspar Capello 54bb39a9d3 Fix tile mode glitch with image brushes 
This fix solves u,v set calculation when 'image brush' are used.

The cause of this bug is that we considered the set m_u, m_v as constants.

We have several cases when we are working on X axis:
- Scanline entirely contained in a tile, but OUTSIDE of the reference tile.
- Scanline entirely contained in a tile, but INSIDE of the reference tile.
- The left side of a scanline which was sliced (by the tile limit).
- The right side of a scanline which was sliced (by the tile limit).
Each one has its own m_u, so we need to recalculate it before every loop->getInk()->inkHline(...).

We have to take similar considerations when we are working in the Y axis.
We need recalculate m_v according if 'y+scanline.y' is INSIDE or OUTSIDE of the reference tile, each case has its own m_v.
