revision 2168:

Fix for shader compilation errors:
global function round requires "#version 130" or later
unable to find compatible overloaded function "texelFetch(sampler2D, ivec2, int)"

revision 2167:

Implemented support for the following PSP video operations in shaders: stencil, color mask, alpha test, blend test.
This shader implementation is improving the compatibility (tested using "3D Studio"), but has a negative performance impact (lower FPS). This is these new functions are available are options in the configuration settings: "enable shader implementation for the Stencil Test" and "enable the shader implementation for the Color Mask". See additional info in the README.txt. These options might improve the graphics display or reveal graphics previously missing.
Improved the viewport implementation to better match the PSP (tested using "3D Studio").
New findings on alpha test parameters.
Improved CLEAR video command.

revision 2166:

Updated the CryptoEngine with new keys (up to firmware 6.39).
Fully implemented sceKernelExtendThreadStack.
Added small new findings to the sceMp4 module.
Added crucial new finding to sceKernelMemset.
Refactored and reorganized several SysMemUserForUser and SysMemForKernel functions.
Fixed several bugs in the ViewportFilter implementation.
