/*******************************************************************************
* vout_scale_t: scaling function
* vout_scale_t: horizontal scaling function
*******************************************************************************
* When a picture can't be scaled unsing the fast i_y_scale parameter of a
* transformation, it is rendered in a temporary buffer then scaled using a
* totally accurate (but also very slow) method.
* This is the prototype common to all scaling functions. The types of p_buffer
* and p_pic will change depending of the screen depth treated.
* The convertion function only perform a vertical scaling. Horizontal scaling
* is done later using this function.
* Parameters:
* p_vout video output thread
* p_pic picture address (start address in picture)
* p_buffer source picture
* i_width buffer width
* i_height buffer height
* i_eol number of pixels to reach next buffer line
* i_pic_eol number of pixels to reach next picture line
* f_alpha, f_beta horizontal and vertical scaling factors
* p_src source address (start address in picture)
* p_dst destination address (start address in picture)
* i_width source width
* i_height source height
* i_line_width source total pixels per line
* i_dst_line_width destination total pixels per line
* i_scale if non 0, horizontal scaling is 1 - 1/i_scale
* Conditions:
* i_height % 16
* i_scale < 0 if p_src == p_dst
