Only enable rasops1_putchar8() and rasops1_putchar16() optomizations on2020-12-21T12:58:42Zketteniskettenis@openbsd.org2020-12-21T12:58:42Zurn:sha1:f614d09e1288fe331d52482c8af73418ddbb0399
big-endian architectectures. These functions assume big-endian bit order
whereas rasops1_putchar() assumes native-endian bit order. Since ssdfb(4)
assumes little-endian bit order and is the only consumer of these interfaces
on little-endian platforms, go with the rasop1_putchar() convention for now.

Optimize character rendering in 32bpp mode, with unrolled rows and2020-07-15T08:34:25Zfcambusfcambus@openbsd.org2020-07-15T08:34:25Zurn:sha1:34a5437d6d5eb86f949663a326352d321a644a36
pairwise foreground / background pixel rendering.
This does double-pixel rendering for the common font widths (8, 12,
16, and 32 pixels wide), resulting in a significant speed-up.
No regression noticed on 32-bit architectures.
Tested by weerd@, and by abieber@ on macppc.
From John Carmack, thanks!
Optimize rasops_vcons_copyrows() so write-only framebuffer consoles2020-07-11T15:02:52Zfcambusfcambus@openbsd.org2020-07-11T15:02:52Zurn:sha1:0464d59668f0aaada84238c6ab0ea92e16ed13e8
only redraw the characters that differ between the start and end
positions. This makes scrolling significantly faster.

change wsdisplay attribute type from long to uint32_t2020-05-25T09:55:47Zjsgjsg@openbsd.org2020-05-25T09:55:47Zurn:sha1:e0c3e5595cd64cda848d09b1c753f51bcbadd436
miod explained it was initially a long as it was thought drivers may
need to allocate storage but in practice they don't need more than
32 bits for an attribute.

rename wsdisplay alloc_attr() to pack_attr()2020-05-25T06:45:25Zjsgjsg@openbsd.org2020-05-25T06:45:25Zurn:sha1:fc223b232cff7e51a9474209d53006b4ae5898e7
Suggested by John Carmack. miod agrees a rename would make sense and
explained it was initially thought drivers may need to allocate storage
but in practice they don't need more than 32 bits for an attribute.
