// File management functions
 - int FileRename(const char *fileName, const char *fileRename); // Rename file (if exists)
 - iint FileRemove(const char *fileName);                         // Remove file (if exists)
 - iint FileCopy(const char *srcPath, const char *dstPath);       // Copy file from one path to another, dstPath created if it doesn't exist
 - iint FileMove(const char *srcPath, const char *dstPath);       // Move file from one directory to another, dstPath created if it doesn't exist
 - int FileTextReplace(const char *fileName, const char *search, const char *replacement); // Replace text in an existing file
 - iint FileTextFindIndex(const char *fileName, const char *search); // Find text in existing file

// Text management functions
 - const char *TextRemoveSpaces(const char *text);                                       // Remove text spaces, concat words
 - char *GetTextBetween(const char *text, const char *begin, const char *end);           // Get text between two strings
 - char *TextReplace(const char *text, const char *search, const char *replacement);     // Replace text string (WARNING: memory must be freed!)
 - char *TextReplaceBetween(const char *text, const char *begin, const char *end, const char *replacement); // Replace text between two specific strings (WARNING: memory must be freed!)

The following code would crash the previous version when calling MemFree:

	// 53 * A
        const char maliciousBase64Input[] = "AAAAAAAAAAAAAAAAAAAAAAAA"
		"AAAAAAAAAAAAAAAAAAAAAAAAAAAAA";
        int decodedSize = 0;
        unsigned char *decodedData = DecodeDataBase64(
		maliciousBase64Input, &decodedSize);
        if (decodedData) {
		MemFree(decodedData);
        }

The reason is a lack of array bound checks in the decoding loop, which
corrupted here the heap (though this is platform dependent).

Adding the bound checks here prevents the memory corruption.

Tested with encoding random data of sizes 0-1023 and comparing it
with the decoded result.

* win32 backend

* [rcore][win32] use SwapBuffers instead of wglSwapLayerBuffers

I don't understand OpenGL well enough to know the difference between
SwapBuffers and wglSwapLayerBuffers but the former seems to double
my FPS (from 2000 to about 4000 in core_vr_simulator).

* [rcore][win32] stop lying to the OS about when our window is updated

Instead of calling BeginPaint/EndPaint in WM_PAINT which signals to the
OS that our window content is updated, now when we encounter the WM_PAINT
message instead we return back to the raylib application which will
trigger it to render a new frame. We've replaced the call to BeginPaint
and EndPaint with a call to ValidateRect in SwapBuffers, which, means
we're now correctly telling the OS when our window content is actually
up-to-date.

Note that this doesn't fix the window content not being updated during
a window resize/move beacuse thos have their own message loop which
doesn't return early when it's time to paint.

* [rcore][win32] fallback to finding functions from opengl32.dll

* [rcore][win32] fixes from review/for gcc

* [rcore][win32] incorporate style conventions

* [rcore][win32] workaround unused function error SetupFramebuffer

* [rcore][win32] re-enable sanitize flags check for MSAA_4X

* [rcore][win32] more style changes and remove old DPI cases

Added some more missing spaces after conditional statements.  Also
made unsupported MSAA_4X an assert instead of an abort and also
removed dpi-aware cases for older OS's.  More changes would be needed
to support those OS versions, namely, removing the dependency
on shcore.

* [rcore][win32] fixes for compling with w64devkit without -DUNICODE

* Update build.zig

* Update build.zig

Fixes a regression since 5.5, where `ScanDirectoryFilesRecursively` no
longer does the "recursively" part due to `path` being `static`.

The issue was once already fixed in
5530a3ceb8
but recently made it back it in.

Found some issues with output size when padding required, just re-implemented both functions from scratch.

Note that returned output size considers the NULL terminator as an additional byte.

- All `char *` refer to text strings
- All `unsigned char *` refer to generic byte arrays
