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.

Examining the code shows that the rectangle is drawn winding counterclockwise, starting
with the top left. Therefore the colors used should be in the order: topLeft, bottomLeft,
bottomRight, topRight.

However, the variables actually being used are topLeft, bottomLeft, topRight,
bottomRight. I was confused by this as I was getting striping where I didn't expect any.
Put another way, the last two parameters are misnamed.

This diff swaps the parameter names and their usages. The result is that no runtime
behaviour changes: the same parameter order yields the same visual result both before and
after this change, but the parameter names now correctly reflect what they are actually
used for.

You can actually see this in the implementation of DrawRectangleGradientV, which
(correctly) passes top, bottom, bottom, top to DrawRectangleGradientEx.

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.

corrected coding conventions.

Bug Fix Update
Code to Ignore Hovering Inputs Completely

It is called on window minification and setting internal width/height to 0, that can break things

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

Make the default font loader early out if we have already loaded parts of it, so we don't leak memory
