4d68f8c53e Render: Allow empty cliprect. 
This fixes an issue where an empty cliprect is treated the same as a NULL
cliprect, causing the render backends to disable clipping.

Also adds a new API, SDL_RenderIsClipEnabled(render) that allows you to
differentiate between:
 - SDL_RenderSetClipRect(render, NULL)
 - SDL_Rect r = {0,0,0,0}; SDL_RenderSetClipRect(render, &r);

Fixes https://bugzilla.libsdl.org/show_bug.cgi?id=2504

03d5719413 Make internal SDL sources include SDL_internal.h instead of SDL_config.h 
The new header will include SDL_config.h, but allows for other global stuff.

23f33cb76c Fixed bug 1622 - SDL_RenderSetViewport with empty SDL_Rect raises wrong error for OpenGL rendering backend 
It's now legal to set an empty viewport rect - it will prevent any rendering.

Also added an API to query the output size: SDL_GetRendererOutputSize()

16cdc59bab Make SDL_SetError and friends unconditionally return -1. 
This lets us change things like this...

    if (Failed) {
        SDL_SetError("We failed");
        return -1;
    }

...into this...

    if (Failed) {
        return SDL_SetError("We failed");
    }


 Fixes Bugzilla #1778.

83c480de5c Whoops, need to actually clip to the viewport in the software renderer. 2011-02-15 14:10:50 -08:00
Sam Lantinga
b59da3ffdc Changed the concept of a render clip rect to a render viewport. 
The render viewport is automatically re-centered when the window changes size, so applications that don't care will not have to handle recalculating their rendering coordinates.

Fixed API for drawing and filling multiple rectangles - the parameter should be an array of rects, not an array of pointers to rects.

Fixed API for updating window rects for consistency with other APIs - the order is pointer to array followed by count in array.

Fixed creating render texture framebuffer.
Removed the need for palette watch, added surface format caching.
Added an SDL_DONTFREE flag so you can't free the window and 1.2 shadow surfaces.

e6ec7f6b28 Fixed bug #1117 
There's a new event that's always sent when the window changes size, and that event is what the renderers listen for to determine if they need to rebind their context.

93a4e38e98 Added a way to get a framebuffer interface for a window, and also a way to create a software renderer for an arbitrary surface. 
The software renderer has been re-routed to use the framebuffer interface, which makes it possible to have software rendering available even on simple ports.

405d4ed7e4 Made it possible to create a texture of any format, even if not supported by the renderer. 
This allows me to reduce the set of formats supported by the renderers to the most optimal set, for a nice speed boost.
