BTextView is actually using, that's why it never used hardware
acceleration for invert rect/region before. Have not tested this on
real hardware yet.

that an error can be propagated back to vm_soft_fault().
* Added boolean restart reference parameter to fault_find_page() which
is set to true whenever a condition is it encountered that requires
to start fault_find_page() from the very beginning. fault_get_page()
checks the flag and executes fault_find_page() in a loop, now.
* Removed the panic()s+TODOs in fault_find_page() when a cache became
busy. The restart feature is used in this case.
* fault_find_page(): If after the loop we haven't found a page yet,
and after locking the right cache one turned up, we restart the
function, too, thus avoiding double insertion of a page into a cache.
* Fixed potential dead-lock in fault_get_page(): After inserting a clean
page into a cache other than the top cache (read fault on
copy-on-write area not backed by a file (e.g. the heap)) the dummy
page was removed from the to be locked top cache while we still held a
lock for the lower cache, thus inverting the locking direction
required by the cache locking policy (top -> bottom).
* fault_get_page(): In case of a write access and a readable page found
in a lower cache, vm_cache_remove_consumer() could have replaced our
dummy page with a real page from a collapsed lower cache while we
had unlocked both caches. We didn't check for this condition and
always inserted our freshly allocated page, thus potentially inserting
a duplicate page into the top cache. We do the check now and discard our
page, when another page turned up. Fixes bug #1359.
* fault_get_page(), same if block: Removed unused case for removal of the
dummy page from a non-top cache. We only ever insert it into the top
cache and it should not be moved to another cache. Added an assert.

* Inode::MayReleaseWriter() would release the semaphore too often; therefore,
Inode::WriteDataToBuffer() now loops in case it still couldn't write anything
instead of failing - this fixes a race condition (ie. a device is full message).
* In case the read request got filled two times (while adding the request, and
after waiting for it to become filled), ReadRequest::PutBuffer() overwrote the
output data. This fixes bug #1331.

before (although there should be much less lock contention)
* with this change, there is quite a bit of cleanup, text drawing is now
about 20% faster than before the original changes to font caching,
mostly due to turning off the kerning feature, which at the moment
gives absolutely no benefit. The correct way of doing it might be to
use kerning depending on the provided glyph spacing mode
* removed fPenLocation from Painter, the usage should be more correct now,
since it is now consistently applied before the coordinate transformation
from view to screen (also for DrawShape() now, before any view scaling
and origin offset)
* Painter no longer has it's own instance of a ServerFont, instead it uses
its AGGTextRenderer instance, which was per Painter again after the
last change, and not global anymore, made _UpdateFont() useless
* When using GlyphLayoutEngine, it supports a second pass with the same
FontCacheEntry through the introduction of a FontCacheReference. This
speeds up DrawString a little, since it needs to calculate the bounding
box for the string, and then draw the string in a second pass. This is
now done with only one FontCacheEntry lookup
* I also tried to optimize the on-the-fly conversion of UTF8->CharCode away,
since it was done four times per DrawString, but surprisingly, it proofed
to be a slight slowdown.
* introduced a shortcut in DrawingEngine::DrawString() which avoids
calculating the bounding box, we are now a tiny bit faster to figure
out that we don't need to draw any string than Dano
In the test environment (drawing to offscreen bitmap and blitting to
screen eventually), text rendering is now about 3.7 times _faster_ than Dano
text rendering (directly to screen), for untransformed text. Unfortunately
I cannot test on the same machine in accelerant using version of the test
environment.

from the store into the top cache, which could lead to pages inserted
multiple times into the cache. We don't insert a dummy page in this case
anymore. Instead we mark a freshly allocated page busy and insert that
one. That's exactly the approach the file cache uses too. This does
probably make the whole dummy page special handling in the file cache
obsolete.

soon as it can.
* No longer put the module image for B_KEEP_LOADED modules - essentially,
that feature was broken.
* Now use the RecursiveLocker in favour of manual locking where appropriate.
This actually fixed two locking bugs in error code paths.
* Applied a patch by François Revol: open_module_list() did not work
when the prefix was already inside a module (as opposed to a directory
on disk). The current solution is not as efficient, but that can be
fixed by improving the iterator code.
