[vdr] Idea - drawing speed-up

[Patrick Gleichmann <patrick@feedface.com>]

Hi,
I wonder if adding a

  #define IS_VISIBLE(COL) (COL & 0xFF000000 > 0)

check would speed up drawing operations (osd.c).
For example:

  void cBitmap::DrawRectangle(int x1, int y1, int x2, int y2, tColor 
Color)
  {
    if (bitmap && Intersects(x1, y1, x2, y2)) {

would become:

  void cBitmap::DrawRectangle(int x1, int y1, int x2, int y2, tColor 
Color)
  {
    if (bitmap && IS_VISIBLE(Color) && Intersects(x1, y1, x2, y2)) {
