2018-09-08GRAPHICS: Simplify trig usage in primitivesDavid Fioramonti
Combined if statements and simplified trig. cos(atan2(y,x)) = x / sqrt(x^2 + y^2) and sin(atan2(y,x)) = y / sqrt(x^2 + y^2).

2018-08-03GRAPHICS: Improve check to test if text fits in the target surfaceBastien Bouclet
When rendering text, especially truetype fonts, we would use the next character avance metric to check if the character fits in the target surface. This commit changes it to use the bounding box metric. The bounding box represents the actual pixels that will be touched when drawing the character. This fixes an issue noticed on the main menu of Myst ME where the last character of the string "OPTIONEN" would not be rendered despite there being enough room to render it. More precisely, this ensures that calling Font::getBoundingBox for a string, and then passing a surface exactly the size of the returned bounding box to the draw function actually renders all the characters.
2018-08-03GRAPHICS: Set thumbnail to nullptr when loading the thumbnail is skippedDavid Fioramonti
Since Graphics::loadThumbnail can return successfully when a thumbnail is skipped the caller may want to check to the see that the thumbnail is not null before using it. Setting it to null is just defensive in case the caller didn't do so. If the user tries to use the thumbnail in setThumbnail then it will just show a black screen for the thumbnail rather than crashing if they have not set the thumbnail to null.

2018-04-07ALL: Load savegame thumbnail only when necessaryAdrian Frühwirth
This commit introduces the following changes: 1. Graphics::loadThumbnail() Now returns a boolean and takes a new argument skipThumbnail which defaults to false. In case of true, loadThumbnail() reads past the thumbnail data in the input stream instead of actually loading the thumbnail. This simplifies savegame handling where, up until now, many engines always read the whole savegame metadata (including the thumbnail) and then threw away the thumbnail when not needed (which is in almost all cases, the most common exception being MetaEngine::querySaveMetaInfos() which is responsible for loading savegame metadata for displaying it in the GUI launcher. 2. readSavegameHeader() Engines which already implement such a method (name varies) now take a new argument skipThumbnail (default: true) which is passed through to loadThumbnail(). This means that the default case for readSavegameHeader() is now _not_ loading the thumbnail from a savegame and just reading past it. In those cases, e.g. querySaveMetaInfos(), where we actually are interested in loading the thumbnail readSavegameHeader() needs to explicitely be called with skipThumbnail == false. Engines whose readSavegameHeader() (name varies) already takes an argument loadThumbnail have been adapted to have a similar prototype and semantics. I.e. readSaveHeader(in, loadThumbnail, header) now is readSaveHeader(in, header, skipThumbnail). 3. Error handling Engines which previously did not check the return value of readSavegameHeader() (name varies) now do so ensuring that possibly broken savegames (be it a broken thumbnail or something else) don't make it into the GUI launcher list in the first place.

2018-03-12GUI: Remove the ThemeItem draw queuesBastien Bouclet
Drawing nows happens directly when the Dialog or Widget draw methods are called. This makes it easy to debug why a particular low level draw method was called, by inspecting the call stack. This replaces the notion of "buffering" by two independant ways to control what is drawn and where: - The active layer is used to select whether the foreground or background part of the dialogs are rendered by the draw calls. - The active surface is used to select if the draw calls affect the back buffer or the screen. The foreground layer of the active dialog is drawn directly to the screen. Its background layer is drawn to the back buffer. This way widgets can restore the back buffer in order to update without having to redraw the dialog's background. Dialogs lower in the dialog stack are drawn entirely to the back buffer.

2017-12-30GRAPHICS: Speed up drawing of rounded square soft shadowsBastien Bouclet
When drawing a rounded rectangle, first its shadow is drawn, and then the rectangle proper is drawn over it. This optimization skips drawing a shadow rectangle that is entirely occluded by the main rectangle. A quick benchmark shows large improvements to the modern theme GUI draw speed. On a 1 GHz ARMv7 CPU with optimizations enabled, drawing the add game dialog @ 1920x1080 went from 976 ms to 136 ms.
2017-12-03ALL: Remove obsolete register keywordColin Snover
The register keyword was deprecated from the C++11 standard, <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4193.html#809>, and removed from the C++17 standard, <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4340>, so cannot exist in a well-formed C++17 program. It has never done anything in GCC <https://gcc.gnu.org/ml/gcc/2010-05/msg00113.html> and because of the way it is specified in the standard, it is “as meaningful as whitespace” <http://www.drdobbs.com/keywords-that-arent-or-comments-by-anoth/184403859>. The one remaining use of the register keyword is in the DS backend, where it is used to create a local register variable using the non-standard GCC Extended Asm feature. Closes gh-1079.
