Fixed bug 3569 - GL_UpdateViewport leaves PROJECTION matrix selected

Tom Seddon

GL_ActivateRenderer may call GL_UpdateViewport, which leaves the GL_PROJECTION matrix selected. But after GL_ResetState, the GL_MODELVIEW matrix is selected, suggesting that's the intended default state.

It seems at least like these should be consistent. Presumably GL_UpdateViewport should be doing a glMatrixMode(GL_MODELVIEW) before it finishes.

    25 /* IMPORTANT:
    26    This is the master switch to disabling the dynamic API. We made it so you
    27    have to hand-edit an internal source file in SDL to turn it off; you
    28    can do it if you want it badly enough, but hopefully you won't want to.
    29    You should understand the ramifications of turning this off: it makes it
    30    hard to update your SDL in the field, and impossible if you've statically
    31    linked SDL into your app. Understand that platforms change, and if we can't
    32    drop in an updated SDL, your application can definitely break some time
    33    in the future, even if it's fine today.
    34    To be sure, as new system-level video and audio APIs are introduced, an
    35    updated SDL can transparently take advantage of them, but your program will
    36    not without this feature. Think hard before turning it off.
