clear_bitmap() call fails to clear bitmap correctly and drawing operations to bitmaps fail

[DarrenGansberg]

Problem Description

Drawing operations to bitmaps are not reflected in changes to bitmaps.

How to reproduce
Create a bitmap by calling create_bitmap(string,int,int), Attempt to draw upon the bitmap or attempt to clear the bitmap to a solid color, by calling clear_bitmap(bitmap, color).

For example:

#include "splashkit.h"

int main()
{
int width = 128;
int height = 256;
bitmap bmp = create_bitmap("mybmp", width, height);

//The colour blue
color c = rgba_color(0.0,0.0,1.0,1.0);

clear_bitmap(bmp, c);

save_bitmap(bmp, "test");
delay(5000);
return 0;
}

Experienced behaviour
Drawing operations are not reflected in bitmaps. For instance, calling clear_bitmap on a bitmap, fails to clear the bitmap to a solid color. Bitmaps when passed to draw_line_on_bitmap fail to result in lines being drawn to a bitmap.

Expected behaviour
Drawing operations are actually reflected in changes to bitmaps. For example, a bitmap passed to clear_bitmap(bitmap, color) would actually be cleared to a solid color. A line drawn upon a bitmap would appear on the bitmap if it is drawn to a window.

Looks like you can solve this at the moment by opening a window before creating and drawing the bitmap. I should have a fix done soon.
