Correction, 2, 8, and 16 bit routines have some accelerated versions. 24bpp
is supported, but there are no specially optimized routines for that
configuration. You could always write some if you need them.
Note that if display performance is a critical piece of your application,
then you really need to be using a display controller that supports hardware
acceleration. Even a minimal amount of hardware acceleration should be much
superior to what you would get with optimized software blits.

Hi,
Currently WinCE provides only GPE emulated routines for
16bpp display format.
Not so sure: on my devices (x86), those routines work perfectly with
24bpp
video modes. Where did you read that?

GPE based display drivers in WinCE have "optimized" software emulated
routines for 16bpp only.
For all other formats, only general routines are there which are not
so good in terms of performance.
For this , one can have a look in "PUBLIC\COMMON\OAK\DRIVERS\DISPLAY"
for reference.
