Generating Texture Data

This function generates a checkered texture on the fly.

This is used on the triangle that will be rendered and rotated on screen.

Generates a checkered texture and stores it in _image.

for (int x = 0; x < imageWidth; x++)
{
    for (int y = 0; y < imageHeight; y++)
    {
        int c = 0;

        if (x % 128 < 64 && y % 128 < 64)
        {
            c = 255;
        }
        if (x % 128 >= 64 && y % 128 >= 64)
        {
            c = 255;
        }

        _image[x][y][0] = c;
        _image[x][y][1] = c;
        _image[x][y][2] = c;
        _image[x][y][3] = 255;
    }
