ff4e1da1f3 Merge branch 'cxx_impl' 
Merge the new video code, which fixes many long-standing issues.
This also implements Video 4 effects and mosaic effect.

4ca45efcc7 Implement Mosaic effect (for all modes and types). 
The effect is not pixel perfect, and the code is slower than non-mosaic
code. However this is intentional to ensure rendering is not very slow.
This improves most games that use this effect, and it's definitely
better than not having it.

1526af3b68 Implement mode 4 color effects 
Modes 3/5 are still not supported and use regular fullcolor path.
Fixes many games, particularly menus and initial sequences for many
other games.

8292786363 Add u1 extension to supported filetypes 
As requested in issue #37 .  Could probably lose the 'v0.91' from the build version as well and just have it report the github build.

8622c43d48 Implement sprite limit 
Accounts for number of cycles per scanline and stops pushing objects
that go over the limit. Reversed processing from high to low priority
and drawing from low to high.

4349668315 Fix ST-OBJ blending 
This uses an extra bit and does proper color stacking when needed to

Fixes most games that had coloring issues finally :)

fef2b89e87 Backport VRAM mirroring issues for OBJ rendering 
When using a big sprite with a tile at the end of the 32KB VRAM block it
might end up reading past the 32KB block. This is not an "issue" since
the VRAM wraps around within the 32KB block.

1ee50ada80 Reimplement sprite copy-mode for obj-based windowing 
Seems it fixes a couple of visual issues in games too.
Might need to re-check that we do not overdraw too much to avoid
performance issues.

30e86961a1 Don't update background scanline params in mode 0 
Noticed that an issue with Rayman 3 Hoodlum Havoc was reported on one of the gpsp compatability lists.  Cross-checked against mgba and revealed the same issue reported as being present in an earlier version -

https://github.com/mgba-emu/mgba/issues/377

This PR applies the same fix as used in mgba.  Could affect other games also.

0db43d6683 Add VRAM mirroring fixes to video code. 
This fix comes from TempGBA-Mod (see PR #217).
