Feature request

Create the function setModeHdmaWindowEx where channel numbers can be passed in parameters:

/*! \fn  setModeHdmaWindow(u8 bgrnd, u8* hdmatableL,u8* hdmatableR)
    \brief Do a window  effect on screen. Use HDAM Channels 4 & 5.
    \param bgrnd background for the windows effect  (value MSWIN_BG1..MSWIN_BG4)
    \param bgrndmask background mask (inside, outside) for the windows effect  (value MSWIN1_BG13MSKIN..MSWIN1_BG13MSKIN)
    \param hdmatableL table with windows effect on the left
    \param hdmatableR table with windows effect on the right
    \param channel1 the channel 1
    \param channel2 the channel 2
*/
void setModeHdmaWindowEx(u8 bgrnd, u8 bgrndmask,u8* hdmatableL,u8* hdmatableR, u8 channel1, u8 channel2);

So it allows to use other channels than the default channels 4 and 5.

Is it possible to create this function?
