m_fStretchTexCoordVelocityX -> TexCoordVelocityX, etc.
Remove TYPE_STRETCH.
Disassociate BGAL::Type from the "Type" BGA metric. Prefer "Type=sprite",
"Type=particles", "Type=tile", and "Stretch=1" (for sprite only). Type=0, 1, 2, 3 still
work; 0 is "Type=sprite", Stretch=0 and 1 is Type=sprite, Stretch=1.
Remove old code.
Historical note: "stretch" was used in this code at various times to mean both 1:
"stretch the internal texture image to fit the texture" and 2: "stretch the displayed
image to fill the screen". It now only means #2. #1 is done automatically when needed.
Note that LoadFromAniLayerFile should never load an INI; it's for backwards-
compatibility only. LoadFromIni is simpler and more flexible.
