Macro to convert palette array entry to u16

[pvmm]

Suppose you can't use VDP_SetPalette because your palette is incomplete. You can use this macro to solve this problem:

    // Set color index i from 1 to 13
    for (int i = 0; i < 13; ++i) {
        VDP_SetPaletteEntry(i + 1, RGB16_FromPal(palette, i));

What is the problem exactly?

Why don't just use casting?

    // Set color index i from 1 to 13
    for (int i = 0; i < 13; ++i) {
        VDP_SetPaletteEntry(i + 1, ((u16*)palette)[i]);

I was confused by this formatting string Format: [0:5|green:3|0|red:3|0|blue:3] so I thought it was ordered differently. But I suppose an explicit conversion makes it more clear to the user?
