Yeah ...

On the other hand, for my 2d module I let users specify texture coordinates using integer coordinates because most people are more comfortable using pixel coordinates when coding with 2d oriented APIs.

In other words I use something like this:

drawSprite(const RectangleI &screenRectangle, const RectangleI &textureRectangle, float scale,float rotate,int origX, int origY,const Color &tint=Color::White)
