PocketMatrix

first, why the Blt function does't support E2DSurfaceRGBA?

second, I want to use BltFast with EFX_COLORIZE && EFX_OPACITY , how to set the property ?

I had try to do it like this, but fail.

buffer->BltFast(100, 100, &m_sprite, NULL, EFX_COLORFILL| EFX_OPACITY, 100<<24 | E_RGBX(0,0,255) );(m_sprite have Alpha)

the screen show me nothing
