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.
Re-fetch texture when cursor's either width or height changed.
When the cursor icon changed and the new one has the same width or height,
it may not recreate the texture and thus cause memory access violation.
Whenever a cursor is captured and the cursor icon changes, it creates a
new texture. This isn't particularly optimal, so instead just store a
cache of cursor textures (based on size), and make the textures dynamic.
Doing this will prevent unnecessary texture reallocation.
This fixes an issue primarily with filter rendering: when capturing
windows and displays, their alpha channel is almost always 0, causing
the image to be completely invisible unintentionally. The original fix
for this for many sources was just to turn off the blending, which would
be fine if you're not rendering any filters, but filters will render to
render targets first, and that lack of alpha will end up carrying over
in to the final image.
This doesn't apply to any mac captures because mac actually seems to set
the alpha channel to 1.
