Fixed warnings for more pedantic settings (#258)

Added GetKeyIndex() helper.

Tweaked scrolling example code (#150)

SetScrollFromCursorPos() -> SetScrollHere() (#150) final call !

Added SetScrollY(), SetScrollFromPosY(). Renamed SetScrollPosHere() to SetScrollFromCursorPos(). (#150)

Renamed GetScrollPosY() to GetScrollY(). (#150) ...

Necessary to reduce confusion along with other scrolling functions,
because positions (e.g. cursor position) are not equivalent to scrolling
amount.

Added GetCursorStartPos() necessary for using scroll target relative to beginning of window content (#150)

Fixed text baseline alignment of small button (no padding) after regular buttons ...

Currently being a coward and only doing it via the SmallButton() entry
point.

Comments + remove trailing comma

Split into CaptureKeyboardFromApp() / CaptureMouseFromApp()

Added CaptureInputsFromApp() to manually enforce e.g. keyboard capturing

Fixed a bug with TextUnformatted() clipping of long text (#257)

SetScrollPosHere() Minor hack for effective "scroll to top" to appear like user expect it (#150) ...

Compensate the difference between WindowPadding and ItemSpacing

Fixed window padding being reported incorrectly for child windows with borders when parent have no borders

SetScrollToPosHere() fixed imprecision + handling lower gap better for bottom alignment (#150)

Added scroll tracking example with SetScrollPosHere() (relate #150)

SetScrollPosHere() takes a y centering ratio and can be used to aim the top or bottom of the window (relate #150)

Title bar uses TitleBgActive color even when window has popups/menus over (#253)

Adding TitleBgActive color - still issues with popups/menus (#253)
