avfilter/drawbox+drawgrid - add option to prevent overwriting of source pixels
If the user-supplied color in drawbox and drawgrid filters is non-opaque,
the box & grid painting overwrites the input's pixels (including alpha).
Users typically expect the alpha of the specified color to only act as a key
for compositing on top of the main input.
Added option allows users to select between replacement and composition.
Tested and documented.
