Subject: [SDL] Frame buffer patches...

Would seem that GCC 3.2.2 promotes all signed values to unsigned if any single vlaue is unsigned in an expression...

for instance when calculating an elo touch position....evertyhign is an (int) except for cach_vinfo.xres which is unsigned. THerefore if y
ou reverse the SDL_ELO_MIN_X and SDL_ELO_MAX_X values the resulging negative value pegs the expression to it's max. Attached it the accumu
lated patch to typecast the unsigned values to (int)

- *dx = (cache_vinfo.xres - (cache_vinfo.xres * (input_x - ELO_MIN_X)) / width);

+ *dx = ((int)cache_vinfo.xres - ((int)cache_vinfo.xres * (input_x - ELO_MIN_X)) / width);

and also to provide quite failure to operations which have the screen currently locked...

The touch screen I'm using the original values were exactly opposite of any position I touched on the screen - evaluating the math the expr
ession SHOULD have handled reversing the min and max values - and after casting the unsigned .xres and .yres to a signed int - worked well.

Subject: [SDL] Request: Please reconsider adding tag in SDL_Event

Hi,

} SDL_SysWMEvent;

/* General event structure */
-typedef union {
+typedef union SDL_Event {
Uint8 type;
SDL_ActiveEvent active;
SDL_KeyboardEvent key;

Reasoning:
----------
1) Allows forward declaration of the SDL_Event union in C++. Please
note that in plain C it is possible to forward declare it.

2) Forward declaration is good because it allows encapsulation. It hides
the specific implementation and does not necessarily exposes SDL staff
to my appication's namespace

3) It can't harm plain C because tags are living in a different namespace
than typenames

4) It is already done like this in other places in SDL. Check for example
SDL_KeySym, and SDL_.*Event structures.

5) Right now I have to include SDL/event.h from a C++ header file. See 2)

[PATCH] SDL_GetVideoMode() does not find best mode, part 2

Following commit 1.51, I come accross a problem when SDL must choose between
several video modes that could suit the one asked.

If I ask 320x240 with this list:
768x480 768x240 640x400 640x200 384x480 384x240 320x400 320x200

The smallest selectables modes are 384x240 and 320x400. And SDL choose the later
in this list, but 384x240 is more suitable. So I added a check to compare
the pixel count (surface) of modes, and select the one which has the smallest
pixel count.

In my example, 384x240 has 92160 pixels, and 320x400 has 128000 pixels. So now
SDL will choose 384x240 for the asked 320x240 mode.
