(This also modifies image-source, obs-text, text-freetype2, and UI)
This improves source definition versioning. To do this, it now stores
two identifier names. One "unversioned" which is the original name, and
one "versioned" with the version number appended.
This fixes both backward compatibility with older OBS versions, and
fixes the inability to use "add existing" in OBS itself on sources
created from older version definitions.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
The GDI+ based Text Source actually uses Premultiplied Alpha. The edges
of the fonts are therefore incorrectly blended, causing ugly artifacts
especially if bright text above a bright background is used. Here's an
image comparing the new text blending (left) to before (right):
Additionally, the game capture has the same problem, so premultiplied
alpha is used there as well now.
Delayed reading the text file till the update after the timestamp
changes, this should fix a minor issue where if the file updates twice
in one second, only the first change it displayed.
Similar to the parent commit, do not reset the blend state if the source
is not marked as a custom drawn source. Filters applied won't have the
correct blend state and the alpha edges of the text will be partially
black.
