Texture Format Selection Rules

When you use a device-independent source image to create a device-dependent texture surface for rendering, the rules are (in order of precedence):

1. Preserve RGB/palettized nature

2. Preserve alpha channel

3. Preserve bit depth or palette size

4. Preserve RBGA masks

5. Prefer 8-bit palettized or 16-bit RGB
