Some configure work:
- removed TEXTURES_ARE_DIRTY logic, and just recreate the GL textures
when a screenmode changes
- enable checking for machine type and if nasm is available
- logic to enable scaler mode only when in OpenGL mode (still not complete
and defaults to off)
First pass at adding scaler code to OpenGL. Still much work TODO,
but the C version is working correctly (asm is causing crashes,
haven't figured out why). GL quad coordinates aren't properly
set yet, so the image always appears in the upper left corner, and
is not scaled to the window size. CPU usage is also quite high,
but I'm on a 1GHz laptop with i950 GL, so that may explain it.
Fixed long-standing bug in software rendering, where switching to a
lower-res screen while a message is being displayed would cause a
segfault.
Large refactoring of mainSDL. Specifically, OSystem now owns all
the subsystems except for Settings, taking responsibility for creating
and destroying them.
Properties fixes for 'Tomarc the Barbarian' and 'Gyruss'.

|

The ColorMasks template can be used to map bit format values
|
||||
(like 555, 565, 1555, 4444) to corresponding bit masks and shift values.
|
||||
Currently this is only meant for
|
||||
|
||||
The meaning of these is masks is the following:
|
||||
kBytesPerPixel
|
||||
-> how many bytes per pixel for that format
|
||||
|
||||
kRedMask, kGreenMask, kBlueMask
|
||||
-> bitmask, and this with the color to select only the bits of the corresponding color
|
||||
|
||||
The k*Bits and k*Shift values can be used to extract R,G,B. I.e. to get
|
||||
the red color component of a pixel, as a 8-bit value, you would write
|
||||
|
||||
R = ((color & kRedMask) >> kRedShift) << (8-kRedBits)
|
||||
|
||||
Actually, instead of the simple left shift, one might want to use somewhat
|
||||
more sophisticated code (which fills up the lower most bits.
|
||||
|
||||
|
||||
The highBits / lowBits / qhighBits / qlowBits are special values that are
|
||||
used in the super-optimized interpolation functions in scaler/intern.h
|
||||
and scaler/aspect.cpp. Currently they are only available in 555 and 565 mode.
|
||||
To be specific: They pack the masks for two 16 bit pixels at once. The pixels
|
||||
are split into "high" and "low" bits, which are then separately interpolated
|
||||
and finally re-composed. That way, 2x2 pixels or even 4x2 pixels can
|
||||
be interpolated in one go.
