* We get the video mode from the target monitor and use that to set, therefore
keeping windowed-fullscreen
* Added a GLFW_AUTO_ICONIFY 0 hint so that glfw does not minimize the window
when changing focus from a windowed fullscreen window. This is more expected
behavior for windowed full screen, when a user alt-tabs or clicks on a window in
the other monitor, they expect their windowed-fullscreen window to remaining up.

We were doing this before, but it was deleted during the
last GLFW update. Readd it to fix the associated macOS CI failure.

Fixes: ea5cd42e6 ("Update GLFW to version 3.4")

Tested on Raspberry Pi... Just note that platform is very limited by GPU...

If press/release events for a mouse button come too fast, then using
`IsMouseButtonReleased()` does not work. This has been noticed when
using a touchpad on Linux when tapping with two fingers two emulate
right mouse button click.

The situation looks like this:

```
BeginDrawing           <-- current==released, previous==released
Pressed                <-- current=pressed
Released               <-- current=released
IsMouseButtonReleased  <-- returns false because current==previous
EndDrawing             <-- previous=released
```

The fix is to update the previous mouse button state in addition to
current mouse button state when `MouseButtonCallback()` is called by
glfw. Now the situation is as follows:

```
BeginDrawing           <-- current==released, previous==released
Pressed                <-- current=pressed, previous=released
Released               <-- current=released, previous=pressed
IsMouseButtonReleased  <-- returns true because current!=previous
EndDrawing             <-- previous=released
```

It seems to work ok on my old Intel HD Graphics card... it should work anywhere else

* fixes for switching full-screen and v-sync

* requireVsync flag

- Renamed GetGlyphIndex() parameter
 - Review DrawTextEx() implementation
 - Review DrawTextRecEx() implementation

* swapped comments, expanded comment for clarity

* revert alignments

* adjusted for consistency

Just simplified code a bit

Actually OpenAL is not used any more, it should be using CoreAudio

Keeping original API

* add api FIFO based character input.

* rename input character functions

* replace tab to space x4 #1012

* Fix camera not working problem at align z direction. #924

* replace tab to space x4

Uses fewer vertexes than using DrawCube() or DrawSphere() for points.  The small line is on analogy to the code for DrawPoint() in shapes.c.

* [rlgl] Create function `rlUpdateMeshAt`

* [rlgl] Update function `rlUpdateMeshAt`

Corrected bug when loading a RenderTexture texture passing NULL data.

At least on Linux, CMake seems to add automatically
the '-rdynamic' flag. As a result, Emscripten
generates a fat HTML file that does not work.
Removing it allows HTML+JS+WASM generation.

* explained a bit more the core_window_letterbox example

* fixed a few 'ups' moments that could lead to mild head pain and time loss

* new linux makefile for Android portages

* Revert "projects: CMake: bump up minimal raylib version (#983)"

This reverts commit 82306af111.

* new PR for upstream

* for Raysan

ADDED: CodepointToUtf8()

RENAMED: TextCountCodepoints() -> GetCodepointsCount()
