There was an error in the other branch of the refactored function where the size of the array was not properly multiplied by the size of the float to check against the buffer size. This was only an error in the error-checking itself and not the functionality. There was also an error where the proper notification was not emitted whenever the buffer for the multimesh is recreated to invalidate the previous references the renderer might've created to it. This fixes CPU Particles getting corrupted when they're created without emission being enabled.
Even if you specify the subsystem to be the console one, the vsproj doesn't carry over the setting, which makes working with this mode in the IDE a bit annoying since it'll regenerate the vsproj right afterwards. Since there's only two options and 'gui' is the default, we only carry over the 'console' setting.
Direct buffer copies are required to perform certain operations more efficiently, as the only current alternative is to download the buffer to the CPU and upload it again. As the first use case, the new function is used when enabling motion vectors on multimeshes.
This is done only in the editor and only on Windows, to avoid a file
lock that prevents the original library being updated (e.g. by a
compiler).
When the game runs it will load the original DLL and pick up any
changes, only the editor will stay with the copy (until it is restarted
and create a new copy).
The copy is done in place by prepending a `~` to the original file name,
so dependencies that are loaded with a relative file path still work.
When the library is unloaded the copy file is deleted. The copy is also
marked as hidden to not show up in explorer.
Integer scaling is achieved (after aspect expansion) by "lying" to the
stretching code about the window's size, telling it that it's always an
integer multiple of the viewport so that it only gets stretched to an
integer factor.
This approach works with all stretch and aspect modes and doesn't
require handling for each, only requiring to "loosen up" some
self-excluding conditions (in other words, replacing some `else if`s
with just `if`s) regarding viewport offset and margin calculation (black
bars).
Includes a tiny usability change that adds a range hint for the content
scale factor between 0.5 to 8.0.
