Squashed commit of the following:
libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
libs/: Fix paths in moved library directories.
libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.

* Name: nxtk_bitmaptoolbar
|
|
*
|
|
* Description:
|
|
* Copy a rectangular region of a larger image into the rectangle in the
|
|
* specified toolbar sub-window.
|
|
*
|
|
* Input Parameters:
|
|
* hfwnd - The sub-window twhose toolbar will receive the bitmap image
|
|
* dest - Describes the rectangular region on in the toolbar sub-window
|
|
* will receive the bit map.
|
|
* src - The start of the source image.
|
|
* origin - The origin of the upper, left-most corner of the full bitmap.
|
|
* Both dest and origin are in sub-window coordinates, however, the
|
|
* origin may lie outside of the sub-window display.
|
|
* stride - The width of the full source image in pixels.
|
|
*
|
|
* Returned Value:
|
|
* OK on success; ERROR on failure with errno set appropriately
|
|
