Moonchild	49a86db5f3	Issue #2040 - Pre-multiply the alpha values in our JXL decode buffer. (uplift) Using selective calculation (only if not opaque) and fast integer math here should optimize well in compilers.	2022-12-15 09:09:19 +00:00
Moonchild	2640953d8b	Issue #2019 - Follow-up: Make nsPluginInstanceOwner also listen to keypress events in the system event group. nsPluginInstanceOwner only listens to keypress events in the default event group. However, in our changed operating mode, keypress events are not fired in the default event group if the key does not result in something printable. This means that nsPluginInstanceOwner should also listen to keypress events in the system event group and should handle each keypress that way, but only once. I.e., if a printable keypress event is received in the system event group, it should be ignored, since it would've already been handled in the default event group in that case.	2022-11-26 18:18:09 +00:00
Moonchild	7eb7d67f7a	Issue #2033 - Temporary fix of R<->B channel swap. We have a BGR/RGB channel ordering mismatch here. to at least provide proper display, a quick&dirty byte swap on the output buffer will fix this for now, but we should look into seeing where the surface mismatch is caused. std::swap() should optimize pretty well in any of the used compilers, but if necessary, a full buffer ASM routine can be slotted in (although on current hardware I doubt this will be even noticeable as it is)	2022-11-26 02:43:18 +00:00
