Nav: added io.ConfigNavCursorVisibleAuto, io.ConfigNavCursorVisibleAlways. (#1074, #2048, #7237, #8059, #3200, #787) 

Note: the NavCursorHideFrames addition is to support 88a354585 even though ConfigNavCursorVisibleAlways is set.

@ -69,20 +69,26 @@ Other changes:
state to draw callbacks. (#6969, #5834, #7468, #3590)
- IO: WantCaptureKeyboard is never set when ImGuiConfigFlags_NoKeyboard is enabled. (#4921)
- Error Handling: turned a few more functions into recoverable errors. (#1651)
- Nav: added NavSetCursorVisible(bool visible) to manipulate visibility of keyboard/gamepad
navigation cursor. (#1074, #2048, #7237, #8059)
- Nav: added io.ConfigNavEscapeClearFocusItem and io.ConfigNavEscapeClearFocusWindow to change
how pressing Escape affects navigation. (#8059, #2048, #1074, #3200)
- Set io.ConfigNavEscapeClearFocusItem = true (default) to clear focused item and highlight.
- Set io.ConfigNavEscapeClearFocusItem = false for Escape to not have a specific effect.
- Set io.ConfigNavEscapeClearFocusWindow = true to completely unfocus the dear imgui window,
is for some reason your app relies on imgui focus to take other decisions.
- Nav: pressing escape to hide nav highlight doesn't clear location from when ctrl+tabbing
back into same window later.
- Nav: fixed Ctrl+Tab so when starting with no focused window it starts from the top-most
window. (#3200)
- Nav: rectangle highlight not rendered for items with ImGuiItemFlags_NoNav. Can be relevant
when e.g activating the item with mouse, then Ctrl+Tabbing back and forth.
- Nav (Keyboard/Gamepad navigation):
- Nav: added io.ConfigNavCursorVisibleAuto and io.ConfigNavCursorVisibleAlways to configure
visibility of navigation cursor. (#1074, #2048, #7237, #8059, #3200, #787)
- Set io.ConfigNavCursorVisibleAuto = true (default) to enable automatic toggling
of cursor visibility (mouse click hide the cursor, arrow keys makes it visible).
- Set io.ConfigNavCursorVisibleAlways to keep cursor always visible.
- Nav: added NavSetCursorVisible(bool visible) function to manipulate visibility of
navigation cursor (e.g. set default state, or after some actions). (#1074, #2048, #7237, #8059)
- Nav: added io.ConfigNavEscapeClearFocusItem and io.ConfigNavEscapeClearFocusWindow to change

- Disabled: clicking a disabled item focuses parent window. (#8064)
- InvisibleButton, Nav: fixed an issue when InvisibleButton() would be navigable into but
not display navigation highlight. Properly navigation on it by default. (#8057)

- font/opt: Glyph currently 40 bytes (2+9*4). Consider storing UV as 16-bits integer? (->32 bytes). X0/Y0/X1/Y1 as 16 fixed-point integers? Or X0/Y0 as float and X1/Y1 as fixed8_8?
- nav: some features such as PageUp/Down/Home/End should probably work without ImGuiConfigFlags_NavEnableKeyboard? (where do we draw the line? how about CTRL+Tab)
! nav: never clear NavId on some setup (e.g. gamepad centric)
- nav: Home/End behavior when navigable item is not fully visible at the edge of scrolling? should be backtrack to keep item into view?
- nav: NavScrollToBringItemIntoView() with item bigger than view should focus top-right? Repro: using Nav in "About Window"
- nav: expose wrap around flags/logic to allow e.g. grid based layout (pressing NavRight on the right-most element would go to the next row, etc.). see internal's NavMoveRequestTryWrapping().
