Modified Files:
bitmap_con.c
Log Message:
Increase max palette size from UINT8_MAX to UINT32_MAX.

Text colours still occupy the lowest 16 values. This increases the size
of the screen array, but allows higher colour depth in the future.

Modified Files:
bitmap_con.c
Log Message:
Exciting new bitmap features

1) Fix last commit. Crashes/Video corruption resolved.
2) Add ccputs() and cputch() to ciolib. These take a colour value as their
first argument, which is a palette entry. They otherwise work the same
as their counterpart without the c prefix.
3) Add a flags member to vstat which needs to be set before loading a mode.
The only defined flag is currently VIDMODES_FLAG_PALETTE_VMEM.
4) If VIDMODES_FLAG_PALETTE_VMEM is set, allocate 32-bit arrays for the
foreground and background palette entries for each cell.
5) Have bitmap_con.c use the palette vmem flag.
6) Have movetext() copy the palette entries along with the regular vmem.

In theory now, bitmap_con.c will handle giant colour palettes, and anything that uses movetext() (ie: scrolling) will maintain the colours.

gettext() and puttext() unfortunately can not access the palette memory... we'll see if we need extended replacements for them or not.

Push update_pixels down and force a redraw on font change.update_pixels should only be set when at least one pixel hasactually been changed... setting it when
pixels have not beenchanged causes unneeded screen updates.Previously, a font change asserted (incorrectly) that the pixels inthe screen had been modified, so the change would occur at the endof the next blink cycle when alt fonts are checked. Now itrequests a full redraw from vmem when a font is changed, which willtrigger a redraw the next time the blinker thread triggers (~5ms).

Another large speedup... only update bitmap when drawing a frame

Previously, every change would be flushed through to the bitmap, now
it only flushes before a frame is sent to the driver, or when specific
things (like setting pixels) occur.

This about doubles the throughput again, running the test at 11
seconds (started at 179). At a 16× speedup now from when I started.

This can now display at about 10Mbps, which is still kinda slow,
but at least it's not completely terrible anymore.

This could likely be improved by better timing of the frame
generation... it tries to hot 100Hz right now, which is a bit
excessive.

This means cursor blink at 3.745Hz, and character blink at 1.8725Hz.

For Prestel, character blink was 0.75Hz with a 3:1 On:Off ratio.
The cursor on the other hand was 1/32th the VSYNC and was generally
PAL, so 1.5625Hz.

Log Message:
Split the happy path font rendering into separate function

And merge the single/double height ones into the same function.
Normalize all the types while I'm here.

With this, the happy path draw_char_row_fast() is very simple and
easy to keep updated, and all of the complexity goes into
draw_char_row_slow().

There seems to be around a 20% performance difference between them,
but it can be hard to tell for sure because of the time spent
cheating.

Note that it doesn't appear to be worth cheating if we're going fast,
but that's getting a bit too deep for my tastes.

Add silly check to make coverity happy.

This is in the fastpath, but it's on the slow side where I don't
mind the occasional extra silly check.
