this might bork the repaint, since isBgRepaintNeeded_ won't be reset to false.
There was a problem hiding this comment.
hmm, that might be true, however the bg repaint would still be needed as it didn't really happen (?)
so now that i looked at the code / msdn docs for a while, it seems that isBgRepaintNeeded is set by the next case item (which is proxying from WM_ERASEBACKGROUND, and from OnSizeUser), with both cases occuring on a resize event indicating that the updateRect shouldn't be empty at all in these cases.
giving some mre tought, setting the flag here to false couldn't hurt (in the case of resizing the panel to 0 width/height)

some minor drawing related fixes:
#define GDIPVER 0x0110instdafx.h: since we're on Win7+ already (needs Vista+). (will be useful for DWrite later, and some other things)js_panel_window.cppDraw/FillUpdateRect: instead of an error, clamp arc_width/height as w/2 and h/2 respectively.
