- Have video from CPU-based pixel scalers transfer to GPU via DMA. Should improve performance on pixel scalers with large scaling sizes, such as HQ4xS and 5xBRZ.
- Add method VideoFilter::SetDstBufferPtr() - allows users to use their own destination buffer instead of having to use the VideoFilter object's internal buffer.
- Delete the Legacy Cocoa port. (Not only was the Tiger build broken in several ways, but all features from the Legacy port have been subsumed into the main Cocoa port now. Therefore, the Legacy port is no longer necessary.)
- Remove the "Xcode 4" and "Xcode 5" project files. These files have been superseded by the one project file "Xcode (Latest)".
- Do a massive cleanup of the #include and header structure.
- Remove a lot of unnecessary dependencies in the headers.
- Make headers responsible for including what they need for themselves. This makes the headers more independent of where they are in the #include order.
- Relocate some structs/classes to more logical locations.
- Clean up some platform-specific #ifdef stuff.
- Add a new developer-oriented build scheme called "OS X App; dev+" to the Xcode4 and Xcode5 projects.
- Add preliminary GDB stub support to the dev+ build. (Use the menu option Tools > Show GDB Stub Control.)
GDB Stub:
- Do some minor cleanup on the GDB stub init code.

add system in EMUFILE_FILE to switch correctly between read/write modes; add system in EMUFILE_FILE to (optionally) track current file position and avoid redundant fseeks - this code is UNTESTED.

add better console feedback when gbagame .sav is being scanned, to make developers less likely to think the emulator is frozen
- Fix bug where video filters weren't preferring to use the GPU by default.
- Display threads now each pull a copy of the video frame from the emulation thread, rather than the emulation thread pushing copies of the video frame to each display thread. (Slight performance improvement when many display threads are used.)
- Do a huge refactor of the display code.
- Add support for shader-based filters.
- New feature: The display pipeline has been separated into three parts - Source --> Pixel Scale --> Output. Different sets of filters may be applied to each part of the pipeline.
- Add the following source filters: Deposterize
- Add the following output filters: Bicubic (B-Spline), Bicubic (Mitchell-Netravali), Lanczos2, Lanczos3.
- Add shader-based equivalents to the following pixel scalers: Nearest 2x, Scanline, EPX, EPX+, Super Eagle, 2xSaI, Super 2xSaI. These will be used instead of the CPU-based scalers if "Run filters on GPU if possible" is enabled (default is enabled).
- Remove the following pixel scalers from the UI: Nearest 1.5x, Nearest+ 1.5x, Bilinear 2x, EPX 1.5x, EPX+ 1.5x. The reasoning behind this is because these pixel scalers aren't necessary due to the automatic sizing of display view to window. Also, the new output filters make it so that running similar pixel scalers along with an output filter will always yield superior results.
