| SPG_bool |
This
is a define that makes the SPG_bool type identical to Uint8.
Booleans in C++ (and any other language) are 8 bits in
memory for architecture reasons, despite the fact that they hold only 1
bit of information.

| SPG_DirtyTable |
{
Uint16 size;
SDL_Rect* rects;
Uint16 count;
Uint16 best;
}
This
is a struct to hold dirty rect information. When you retrieve the
front table using SPG_DirtyUpdate(), you should loop over the table to
replace the background image.
Example:
SPG_DirtyTable* table = SPG_DirtyUpdate(screen);
int i;
for(i = 0; i < table->count; i++)
{
// Blit background to table->rects[i]
SDL_BlitSurface(mybackground, &bgrect, screen, &(table->rects[i]);
}

| SPG_Point |
{
float x;
float y;
}
A struct to hold coordinate data (position, velocity, etc.). It can be initialized like so:
SPG_Point mypoint = {30, 40};
or
mypoint = SPG_MakePoint(30, 40); |
