win32_utf8: support for setting window titles supporting multiple code pages
Win7FileDialog supports multi-selection -- from 9f229521, b78acebd
Added WDL_ChooseFileForOpen2 for multi-selection with multi-path support (vista+) so that existing code calling WDL_ChooseFileForOpen() with multi-selection enabled remains unchanged (i.e. multi-selection in a single folder) -- from 3cd1b241
SWELL: added ListView_SetItemCountEx() -- from c72a3d48
LICE test app: fixed win32 compile, more benchmark code, run timer at 1ms rather than 16ms -- from a64c6246, 5b8b3acd
LCF: small tweaks to remove warnings, unused vars -- from c7af6b10
eel_lice: added doc for gfx_ext_retina -- from ceef48f8
LICE: constifcation of read pointers for blit functions -- from fe99f35c
LICE: filtering code optimizations (we can assume fractional parts are unsigned and 16 bit, avoiding many cdq/add pairs) -- from 5c2f082e
LICE: optimization to various combining functions.
LICE: blit functions use shifts rather than divides for fixed point calculations
LICE: more constifications -- from 84beb214
LICE: fixed a potential bug with flipped bitmaps and scaled, unfiltered, copy blit -- from aef8e14b
Plush2: when doing certain color/blend combinations and negative-value rounding behavior is not crucial, favor speed -- from 5b10fbe9
WDL_Mutex: on posix, use a recursive pthread_mutex rather than separate counter/owner state -- from ec2b5cf7
HeapBuf/TypedBuf: ResizeOK() return pointer, or NULL on failure, rather than bool -- from 8ef39240
WDL_Queue: simplified memory allocation using ResizeOK -- from 8648f543
TypedQueue: better handle Advance(negative) and error cases -- from 5cb2c936
