ui: Added some missing functionality:
* Added an option to copy input device IDs to the relevant menus.
* Added an item for setting the software lists files path (-hashpath) to
the folder setup menu.
* Allow pasting text from clipboard in most places that allow typing
(searching, entering filenames, entering barcodes).
* Changed the software selection menu heading to be a bit less
misleading.
* Made barcode menu less eager to rebuild itself unnecessarily, and
removed some confusing and apparently pointless code.
Exposed more Lua bindings:
* Added low-level palette objects.
* Added indexed bitmap types.
* Added a bitmap method for extracting pixels from a rectangular area as a
packed binary string.
* Changed screen device pixels method to return width and height in
addition to the pixels.
osd: Added some functionality and cleaned up a little:
* Added a function for copying text to the clipboard.
* Moved function for converting Windows error codes to standard error
conditions to winutil.cpp so it can be used from more places.
* Removed duplicate declaration of osd_get_clipboard_text and made the
function noexcept (including fixing implementations).
* Made macOS implementation of osd_get_clipboard_text skip the encoding
conversion if it finds UTF-8 text first.
* Changed the default -uimodekey setting so it doesn't lose the "not
shift" that stops the default from interfering with UI paste.
Various bug fixes:
* util/unicode.cpp: Fixed the version of utf8_from_uchar that returns
std::string blowing up on invalid codepoints.
* util/bitmap.h: Fixed wrapping constructors for indexed bitmaps taking
the wrong parameter type (nothing was using them before).
* util/bitmap.cpp: Fixed potential use-after-free issues with bitmap
palettes.
* emu/input.cpp, emu/inputdev.cpp: Log 1-based device numbers, matching
what's shown in the internal UI and used in tokens in CFG files.
* emu/emumem.cpp: Added the bank tag to a fatal error message where it
was missing.
docs: Reworked and expanded documentation on configuring stable
controller IDs.
For translators, the changes are quite minor:
* There's a menu item for copying a device ID to the clipboard, and
associated success/failure messages.
* There's the menu item for setting the software list file search path.
* One of the lines in the software selection menu heading has changes as
it could be interpreted as implying it showed a software list name.
* Case sensitivity training for INI (nw)
The world is not 100% Windows, so case sensitvity is needed.
* Further standardization of the formatting (nw)
More to go...
* Pass 2 of new formatting wave (nw)
More to go, though.
* wave 3 of formatting cleanup (nw)
Further adjustments and cleanups, including unwanted tabs.
* Correct filtering instructions (nw)
This change adds id() property to input_device, which represents the
unique device id. This allows the osd layer when creating a device to
pass a friendly display name along with a unique identifier.
Currently the device id is only used to map a physical controller device
to controller id, but can be used more generally in the future. For raw
input devices, we use the full raw input name as the device id. For all
other devices, we fall back to device name as the device id. The
"uniqueness" of the device id is not currently enforced in code.
This change adds support for configuring device to conrtoller id. This
allows for stable controller ids even if USB devices are plugged /
unplugged, system is rebooted, etc.
See documentation for additional context.
