// the objective being that the shift+arrows shortcuts move the texture by the corresponding grid size
// this depends on a scale value if you have selected a particular texture on which you want it to work:
// we move the textures in pixels, not world units. (i.e. increment values are in pixel)
// depending on the texture scale it doesn't take the same amount of pixels to move of g_qeglobals.d_gridsize
// increment * scale = gridsize
// hscale and vscale are optional parameters, if they are zero they will be set to the default scale
// NOTE: the default scale depends if you are using BP mode or regular.
// For regular it's 0.5f (128 pixels cover 64 world units), for BP it's simply 1.0f
