* Initial fixes for last release of libnx For now, the framebuffer aren't okay but it will not crash/ * Improve code reaadability in NvFlinger parsing * Make surfaces access more userfriendly * Add ColorFormat * Fix code style in ColorFormat.cs * Add multiple framebuffer support in nvnflinger This fix libnx console rendering * Move ReadStruct/WriteStruct to Ryujinx.Common * fix the last nit * Fix inverted color for R5G6B5 Also add some other format that libnx might uses. * Remove hardcoded BlockHeight in nvflinger
